What is a standard inductor, including its structure, characteristics, working principle, applications, testing, installation, usage, and development history 2

3. Working Principle:

The working principle of a standard inductor is based on the definition of inductance, which states that when current flows through a coil, a magnetic field is generated around the coil, inducing a voltage within the coil. According to the definition of inductance, the inductance value equals the ratio of the rate of voltage change to the rate of current change. A standard inductor calculates the inductance value by measuring the voltage and current within the coil.

IV. Application:

Standard inductors are widely used in the following fields:

1. Electronic Measurement: Used to measure the inductance value of inductors to verify the accuracy of circuit design.diode

2. Telecommunications field: Used to adjust and calibrate inductive components in communication equipment, ensuring communication quality and stability.

3. Computer field: Used to test and calibrate inductive components on computer motherboards to ensure the stability and reliability of computer operations.

V. Inspection:

The testing of standard inductors typically includes the following aspects:

1. Inductance measurement: Compare the standard inductor with the inductor under test to measure its inductance value.diode

2. Frequency Response Testing: By varying the frequency of the input signal, the response characteristics of the standard inductor are measured to verify its frequency range and accuracy.

3. Coil Integrity Inspection: Check whether the coil of the standard inductor is intact and free from faults such as broken or short-circuited wires.diode
