What is a standard inductor, the structure, characteristics, working principle, applications, testing, installation, usage, and development history of a standard inductor 4

The use of standard inductors generally follows the following steps:

1. Turn on the power: Connect the power supply of the standard inductor and ensure that the power supply voltage and current meet the equipment requirements.diode

2. Connection line: Connect the tested inductor correctly to the input terminal of the standard inductor, and connect the output terminal to the measuring device or data acquisition system.

3. Zeroing and Calibration: Follow the instructions for using standard inductors to perform zeroing and calibration operations to ensure the accuracy of measurement results.diode

4. Start measurement: Select the corresponding measurement parameters and range according to the measurement requirements, and start measuring the inductance value.diode

5. Result processing: Record the measurement results and perform necessary data processing and analysis.

7、 Development history:diode

The development history of standard inductors can be traced back to the late 19th and early 20th centuries. At that time, the main use of inductors was as transmission equipment for telecommunications lines in the telecommunications industry. With the development of electronic technology, the application fields of inductors are gradually expanding.

In the 1930s, with the rise of wireless technology, inductors began to be widely used in wireless receiving and transmitting equipment. These inductors are typically composed of coils and iron cores, used for tuning and filtering signals in circuits.diode
