What is an inductor, common faults and preventive measures of inductors 2

3. Inductive loss fault

Inductive loss fault refers to the decrease or failure of the inductance value of an inductor during operation due to the loss of materials inside the coil. This type of malfunction is generally caused by aging or loss of iron core material in the coil. The detection method for inductive loss faults is to use an LCR meter to test the inductance value of the inductor. If the inductance value is smaller than the normal value, it indicates that there is an inductive loss fault in the inductor.diode

4. Inductor withstand voltage fault

Inductor withstand voltage fault refers to the decrease or failure of insulation performance of an inductor during operation due to aging or loss of insulation material inside the coil. This type of malfunction can easily cause serious consequences such as inductor short circuit or fire. The detection method for inductor withstand voltage fault is to use a high-voltage tester to test the withstand voltage performance of the inductor. If the withstand voltage value is smaller than the normal value, it indicates that the inductor has a withstand voltage fault.diode

3、 Preventive measures for inductors

1. Pay attention to the usage environment of inductors

Inductors are highly sensitive electronic components that are susceptible to environmental influences. Therefore, when using inductors, attention should be paid to avoiding environments such as humidity, high temperature, and strong magnetic fields to avoid affecting the operation of the inductor.diode

2. Using appropriate inductors

When designing a circuit, appropriate inductors should be selected based on the characteristics and needs of the circuit. If the circuit needs to withstand high voltage, inductors with high withstand voltage performance should be selected to avoid inductor failure due to insufficient withstand voltage.diode
