Technical FAQ
Inductor is a passive electrical component composed of coils, which is used for filtering, timing and power electronic applications. It is an energy storage component that can convert electrical energy into magnetic energy and store energy. It is usually indicated by the letter "L".
Please contact us for further information.
The inductor mainly plays the role of filtering, oscillation, delay and notch in the circuit, as well as filtering signals, filtering noise, stabilizing current and suppressing electromagnetic interference.
Please contact us for further information.
The main paramenter of inductor includs mount type, size, inductance, resistance, current,working frequency.
Please contact us for further information.
It helps if you can identify what application the part is being used in. For example, some inductors may be used as common mode chokes and some inductors may be used as power choke, filter choke. Knowing the application, helps select the proper core geometry and size.
Please contact us for further information.
The operating frequency of any magnetic component is a key parameter. This helps the designer determine what possible core materials can be used on the design. It also helps determine the size of both the core and wire as well.

6.1 Open the circuit, use the multimeter to beep the gear, and the sound of the meter proves that the circuit is good. If there is no sound, it means that the circuit is open, or it is about to open, it can be judged as damaged.
6.2 Abnormal inductance is also considered as damage
6.3 Short circuit, which will cause electric leakage
