Electronic components are the components of electronic components and small-sized machines and instruments, which are often composed of several parts and can be used in similar products.
Common electronic components include resistors, capacitors, diodes, triodes, inductors and other devices. In general circuits, common codes are as follows:
1. Resistance resistance is represented by “R” plus numbers in the circuit. For example,’ R7′ means the resistance numbered 7. The main functions of resistance in the circuit are shunt, current limiting, voltage dividing,
Bias, filtering (combined with capacitor) and impedance matching, etc. There are two main methods to identify the resistance: the number mark method: mainly used for small-volume circuits such as SMD.
Color coding method: usually used for color ring resistors. 2. Capacitance Capacitor is generally represented by “C” plus a number in the circuit. The capacitor is made up of two metal films abutting against each other.
An element separated by an intermediate insulating material. The characteristic of capacitor is mainly to block direct current and alternating current. There are two methods to identify the capacitance, namely, color coding method and digital coding method.
