Classification of electronic components

Electronic components are abbreviations of different types of electronic instruments. Next, please contact Wuxi Jingzhe Technology Co., Ltd!

resistance

Resistance in the circuit with "R" plus numbers, such as: R1 represents the number of 1 resistance, the main role of resistance in the circuit is: shunt, current limiting, partial voltage, bias, etc.

capacitance

Capacitance in the circuit is generally represented by "C" plus a number (for example, C13 represents the capacitance numbered 13). Capacitance is composed of two pieces of metal film close to each other, separated by insulating material in the middle. The characteristic of capacitance is to separate direct current and alternating current.

The capacity of a capacitor represents the amount of electric energy that can be stored. The blocking effect of the capacitor on the AC signal is called capacitive reactance, which is related to the frequency and capacitance of the AC signal.

Crystal diode

Crystal diodes are usually represented by "d" and numbers in circuits, for example, D5 is the diode with number 5.

Function: the main characteristic of diode is unidirectional conductivity, that is, under the action of forward voltage, the on resistance is very small; while under the action of reverse voltage, the on resistance is very large or infinite.

Because diode has the above characteristics, it is often used in the circuits of rectification, isolation, voltage stabilization, polarity protection, coding control, frequency modulation and squelch in cordless telephone.

Inductor

Although inductors are not widely used in electronic production, they are equally important in circuits. We think that inductor, like capacitor, is also a kind of energy storage element, which can convert electric energy into magnetic energy and store energy in magnetic field. Inductor is represented by the symbol L, its basic unit is Henry (H), commonly used as the unit of millihene (MH). It often works with capacitors to form LC filters, LC oscillators, etc. In addition, people also make use of the characteristics of inductance to make choke coil, transformer, relay and so on.

Combinational circuit

Integrated circuit is a kind of device with certain functions, which is formed by integrating transistor, resistor, capacitor and other components on silicon substrate with special technology. It is abbreviated as IC, also known as chip.
