For capacitive divider power supply circuit only contains a few simple components, so its structure is simple and reliable. In this circuit, the most important electronic component is the resistive capacitive buck capacitor. Should the capacitive divider power supply capacitor be an X2 capacitor or a CBB capacitor?

The answer is: X2 capacitors and many CBB capacitors can be used as resistance capacitance step-down capacitors.

X2 safety capacitor specifically designed for capacitive divider power supply

X2 capacitors are mainly used to suppress electromagnetic interference from power sources. Ordinary X2 capacitors cannot be used as resistance capacitance step-down capacitors, otherwise there will be problems such as rapid capacity decay and extremely short service life.

1, If you want to use it in capacitive divider power supply circuits, you must use WFC-A series capacitors specifically designed for resistive capacitive divider.

The X2 safety standard capacitor for resistive capacitive voltage reduction is a type of capacitor used in resistive capacitive voltage reduction circuits, which has excellent electrical and stability performance. This type of capacitor usually uses high-quality dielectric materials and electrode materials, which have the characteristics of high withstand voltage, low loss, good stability, long service life, and comply with safety standards, with safety and reliability.

2. CBB22 capacitor specifically designed for resistive capacitive voltage reduction.

In order to avoid oxidation of the metal coating caused by high voltage communication, the CBB22 capacitor specifically designed for resistive capacitive voltage reduction uses different metal thin films, which can significantly slow down the decay rate of the capacitance value. At the same time, the production process is more complex and must be carried out in a constant temperature and humidity workshop to reduce the water content of the production environment and minimize the adsorption of moisture by the product. The zinc aluminum film capacitor core is immediately sealed after heating up, and the product temperature is increased while being evacuated and cured.

3. MPB box capacitors specifically designed for capacitive divider power supply

This type of capacitor is similar to the CBB22 capacitor, with the same internal capacitor core, except that the MPB capacitor has better performance and longer lifespan.

X2 safety capacitors are mainly divided into two types: one is anti power electromagnetic interference, and the other is resistance capacitance voltage reduction. Today, we will focus on introducing the X2 safety capacitors specifically designed for resistance capacitance voltage reduction.

The X2 safety capacitors used for voltage reduction and the capacitors used for anti-interference, although both are made by winding metalized polypropylene film, still have certain differences in their internal composition.

The main adjustment is to adjust the zinc aluminum ratio of the metal film, and at the same time, the resistance capacitance voltage reduction X2 safety capacitor adopts a double 85 characteristic metalized polypropylene film and epoxy resin cured sealing adhesive.

https://www.weetcap.com/Plastic-Film-Capacitors/WEET-WFC-X2-Metallized-Polypropylene-Film-Capacitor-310VAC.html

This is used in resistive capacitive buck circuits, which means that the capacity decay is smaller and the lifespan of the capacitor is longer.

Can ordinary anti-interference X2 capacitors be used in resistive capacitive buck circuits? Indeed, there have been some customers who are not familiar with X2 capacitors and directly use ordinary X2 capacitors for anti-interference in resistive capacitive voltage reduction circuits. The result is that their capacity decays quickly. After a few months of use, due to the severe capacity decay of X2 capacitors, the power supply to the resistive capacitive voltage reduction circuit is insufficient, and the electrical appliances cannot be used normally.

What are the characteristics and functions of the X2 capacitor for resistive capacitive voltage reduction? 

We call the optimized series X2 certified AC safety capacitors for resistance capacitance voltage reduction. They use polymer polypropylene film dielectric, thickened metalized electrodes, fully automatic spray welding process, 94V0 flame-retardant PBT plastic shell, moisture resistant epoxy resin sealing, and CP wire lead out. High voltage resistance, moisture and heat resistance, low capacitance drop, specifically designed for resistive capacitive voltage reduction circuits, such as LED driver modules, electric meters, small household appliances and other low-power electronic consumer products.

Reminder: When choosing X2 capacitors in the future, it is important to clarify whether they are used for anti-interference or resistive capacitive voltage reduction applications. If using resistive capacitive voltage reduction circuits, X2 safety capacitors specifically designed for resistive capacitive voltage reduction must be used, otherwise the circuit is prone to problems.

X2 safety capacitors are commonly used in power circuits to suppress electromagnetic interference. They are installed between the live and neutral wires of the power supply to filter out high-frequency noise, ensure the stability of the power supply, and reduce the potential impact of electromagnetic interference on other electronic devices.

In fact, X2 safety capacitors can be further divided into many types. Taking the WFC-A series X2 safety capacitors from WEET as an example, they can be divided into suppression of power electromagnetic interference type, PD fast charging dedicated type, resistance capacitance voltage reduction dedicated type, double 85 type, moisture-proof type, etc.

In what occasions are moisture-proof X2 safety capacitors used?

This X2 capacitor is suitable for capacitor voltage reduction circuits connected in series with power sources, such as smart meters, LED power supply modules, and other harsh application environments.

What are the characteristics of moisture-proof X2 safety capacitors?

1. The capacity attenuation is extremely small.

Compared with the anti-interference X2 capacitor, our moisture-proof X2 capacitor has less capacity attenuation and can be used in harsh environments such as high temperature and high humidity for a long time with excellent capacity stability.

The moisture-proof X2 capacitor was designed with long-term stability in mind, with minimal capacity decay and the ability to provide stable performance throughout the entire lifespan of the device.

2. Capacitors have self-healing properties and can withstand surge voltage impacts.

3. Excellent flame retardancy and better high-temperature resistance.

4. Better high temperature resistance. The moisture-proof X2 safety capacitor can operate stably in high temperature environments, and its design considers performance maintenance at high temperatures to ensure that there will be no performance degradation or capacity degradation under long-term high temperature loads.

5. Better moisture resistance.

Due to the fact that some electronic devices may be used in humid environments, these capacitors typically have good moisture resistance and can maintain stable electrical characteristics in high humidity environments.

The tuning fork quartz crystal or clock crystal is one of the oldest quartz crystal designs. Originally used for timekeeping in watches and clocks, tuning forks are now also used in modern electronic products such as computers as real-time clocks (RTCs). Hundreds of millions of these uniquely shaped quartz crystals are produced by global suppliers every year. Tuning fork crystals are available in a variety of sizes to meet design needs, and there is a trend towards smaller surface mount crystal packages every year.

Tuning Fork Quartz Crystal (also known as cylindrical crystal oscillator) refers to a crystal oscillator with a quartz crystal wafer that looks like a tuning fork. It is a quartz crystal resonator that is often used to provide clock frequencies to ensure that electronic devices can work properly. The common frequency of tuning fork crystal oscillators is 32.768KHZ, and the main sizes are ‌DIP:3.0x8.0mm(WQC-TF308), 2.0x6.0mm(WQC-TF206), and are commonly used in remote controls, quartz watches, clocks, computers, home appliance automatic control and industrial automatic control, etc.

As the name suggests, quartz crystals are made of quartz. Traditionally, quartz is a naturally occurring hard mineral, but most quartz today is grown synthetically in autoclaves, which provides a higher standard purity than natural quartz. Quartz is used because it becomes piezoelectric and generates an electrical charge when mechanical pressure and tension are applied. This pressure causes mechanical vibrations that we call frequency.

Quartz needs to be cut at precise angles to initiate specific vibration modes and ensure that the piezoelectric effect works. One of the most common crystal designs is the AT Cut crystal. The frequency of an AT Cut crystal is determined by the thickness of the crystal. For example: the thinner the crystal, the higher the frequency. The vibration quality of the crystal will directly determine whether a parallel or series resonant crystal is required for the crystal oscillator circuit design.

The most common quartz crystal frequency is 32.768kHz. This frequency has become common because when 32.768kHz is divided by 2/15, there is a 1Hz signal. This 1Hz signal will always provide a second. This provides a reliable timekeeping system for the advent of days, dates, and times. The frequency of the classic tuning fork is ultimately a result of simple arithmetic operations and the general conditions of quartz production.

The tuning fork crystal is named because its quartz oscillator is cut into the shape of a tuning fork. It is not because its appearance resembles a tuning fork as some people say on the Internet. Due to technical and process reasons, early tuning fork crystal oscillators were mostly cylindrical, which gave many people the misunderstanding that tuning fork crystal= cylindrical crystal.

With the continuous miniaturization of electronic products, higher requirements are placed on the external dimensions of tuning fork crystal. Tuning fork crystals using surface mounting have also appeared.

WQC-TF206 32.768KHZ quartz crystal/tuning fork crystal/clock crystal/TV crystal/cylindrical crystal is most suitable for relatively economical electronic products, such as children's toys, ordinary household appliances, and can make the product highly reliable even in the field of automotive electronics. It can also be used for the CPU clock signal source part of the safety control device, just like the quartz crystal on the clock microcontroller. Under extremely harsh environmental conditions, the crystal can also work normally, with stable oscillation characteristics, high heat resistance, heat cycle resistance and vibration resistance and other high reliability performance.

The design of the electrode of the quartz crystal product has the following functions for the quartz crystal components: 1. Change the frequency; 2. Lead the electrode to the outside world; 3. Change the resistance; 4. Suppress the noise. Items 1, 2, and 3 are relatively simple, and the design of item 4 is very critical. The shape, size, thickness, and type of electrode (such as gold, silver, etc.) will lead to changes in item 4. In particular, as the size of the crystal chip decreases, there are higher requirements for the shape, size, and accuracy of the chip electrode design---the consistency of the tolerance size and position has an increasing impact on the crystal product, so more precise requirements are put forward for the design of the electrode, quartz watch crystal for clocks, cylindrical package crystal.

WQC-TF206 and WQC-TF308 are direct-insertion ordinary tuning fork crystal resonators (quartz crystal resonators, passive crystal) launched by WEET, which are packaged in metal shells. Their frequencies are both the commonly used frequency of 32.768KHz, and the inflection point temperature is 25±3℃ (the frequency changes the least with temperature near the inflection point), which is very suitable for personal computers and clocks.

These two direct-insertion crystal resonators have low power consumption, and the typical value of the excitation power is only 1.0μW; the commonly used load capacitance is 6pF, 7pF, 9pF, 12.5pF; the frequency tolerance at 25℃ is ±10ppm, ±20ppm.

Product features of TF-206 and TF-308 direct-insert crystal resonators:

Resistor welding type crystal resonator

Standard frequency of 32.768 KHz

Higher frequency pull (change in crystal frequency caused by changes in load conditions) and lower equivalent series resistance (ESR);

Low cost, which can greatly improve production capacity

Pb-free, RoHS compliant

DB107S products are widely used in various household appliances such as switching power supplies, LED lighting, integrated circuits, mobile communications, computers, industrial automation control equipment, automotive electronics, LCD TVs, IoT, smart homes, medical instruments, induction cookers, etc.

https://www.weetcap.com/Diodes-Rectifiers/WEET_DBS_DB101S_THRU_DB107S.html

The difference in usage between MB6S and DB107S: MB6S is a rectifier bridge that operates in the mid to low frequency range, while DB107S is a high-frequency rectifier bridge that operates in the tens of kilohertz range. 

Therefore, in order to replace the fast diode SS14, DB107S must be chosen instead of MB6S. 

A rectifier bridge is a device that encapsulates the rectifier tubes within a casing. Divided into full bridge and half bridge. 

A full bridge is a circuit that seals four diodes of a connected bridge rectifier circuit together. 

Half bridge rectifier is a circuit that combines half of two diode bridge rectifiers together. 

Two half bridges can form a bridge rectifier circuit, and one half bridge can also form a full wave rectifier circuit with a transformer and a center tap. 

When selecting a rectifier bridge, consideration should be given to the rectifier circuit and operating voltage.
