What is an inductor, common faults and preventive measures of inductors 1

1、 The concept of inductor

Inductor CC2530F256RHAR is an electronic component whose main function is to generate induced electromotive force in a circuit, resist changes in current, and store energy. An inductor consists of a coil, an iron core, and terminals. The coil is the main body of the inductor and is usually composed of wires wound around a magnetic iron core. In a circuit, the function of an inductor is similar to that of a capacitor, but it stores magnetic field energy rather than electric field energy. The unit of an inductor is Henry (H), which refers to the induced electromotive force of 1 volt generated in the inductor when the current change rate is 1 ampere per second.diode

2、 Common faults of inductors

1. Short circuit fault

The main cause of inductor short-circuit fault is a broken or short circuited winding in the coil. This type of malfunction can cause the inductor to lose its inductive function, thereby affecting the operation of the entire circuit. The detection method for short-circuit faults is to use a multimeter to measure the resistance value between the two ports of an inductor. If the resistance value is 0 or extremely small, it indicates that the inductor is short circuited.diode

2. Open circuit fault

The main reason for open circuit faults in inductors is that the wires or windings in the coil are cut off, which prevents current from passing through the coil and affects the operation of the circuit. The detection method for open circuit faults is to use a multimeter to measure the resistance value between the two ports of an inductor. If the resistance value is infinite, it indicates that the inductor is open circuit.diode
