WEET Tells How to Quickly Grasp the Necessary Electronic Components for IoT Design
At
the time when the Internet of Things (IoT) is booming, a variety of
novel electronic product designs are sprouting, and equipment developers
are making every effort to speed up product development and time to
market in order to seize market share as soon as possible. With the
increasingly fierce competition in the market, understanding how to
quickly grasp the necessary electronic components for IoT design, as
well as the important evaluation indicators and techniques for selecting
relevant components, is of vital importance to promoting product
launches.
Package:
The packaging of
electronic components refers to how the parts are mounted on the circuit
board. Many parts are either soldered on a printed circuit board (PCB),
through a through-hole method, or using surface mount technology.
Basic Electronic Components:
The
simplest components are discrete passive components. These parts have
only a single function, such as providing resistance, capacitance,
inductance, or adding voltage or current control. Most discrete
components have only two to three pins.
Capacitor:
Capacitors
store charge. Capacitors are mostly used for frequency filtering. Its
unit is Faraday, F. Can use through hole or SMT package. The
electrolytic capacitor has polarity and must be installed correctly,
otherwise the capacitor may be damaged. When purchasing a capacitor, you
must declare the polarity, type of dielectric (such as ceramic,
plastic, paper, etc.), rated voltage and capacitance.
Diode Rectifier:
The
diode rectifier can allow or block the flow of current in the circuit
according to the voltage across it. Current is only passed when the
anode voltage is higher than the cathode, and usually needs to be at
least 0.7 volts higher. The diode is like a one-way valve, preventing
the voltage from going in the wrong direction.
It is used for
current conversion from AC to DC to prevent out-of-range input voltage.
Zener diode is a special type of diode used as a voltage regulator.
Schottky diodes have lower forward voltage drop (in the range of 0.15 to
0.45V) and faster turn-on time.
Transistor:
The
transistor is a multifunctional circuit element. This three-pin device
can be used as a voltage or current dependent switch, or as an amplifier
or stabilizer depending on the circuit. There are two main
technologies, bipolar junction (BJT) and field effect (FET). The pin
terminals of these two types of transistors are different. BJT
transistors are divided into two types according to the polarity of the
components, NPN and PNP. FET transistors also have many classifications
based on n-channel and p-channel.
