Finally, in analog circuit current filter circuits, the device is used to filter out high frequency noise of the current in a circuit.

Working Principle

The working principle of a fixed inductor is based on the principles of electromagnetism. When current passes through a coil of wire, the electromagnetic field generated by the coil induces voltage in an opposing coil of wire. This is known as mutual inductance. This voltage is known as the induced electromotive force, or EMF. In order to take advantage of this phenomenon in an electrical circuit, two coils are connected in series. The first coil is called the primary, and the other is called the secondary. When current passes through the primary, a voltage is induced in the secondary. This process can be used to step up or step down the voltage in a signal. It can also be used for filtering or impedance matching.The CDC4D20NP-222KC fixed inductor is based on this principle. It is designed to provide a wide range of inductances and circuit parameters, such as quality factor, frequency response, and input and output impedances. Its low DC resistance, IDR, and low current fluctuation make it an ideal choice for a variety of applications.

Conclusion

The CDC4D20NP-222KC fixed inductor is an advanced device that is used in a variety of circuits. Its small size, excellent reliability, high temperature resistance, shock, vibration, and radiation resistance make it suitable for a variety of power amplifier, EMF or electromagnetic field interference signal filter, and communication device power supply filter circuits. Its working principle is based on mutual inductance, which it uses to step up or step down a signal, as well as for filtering and impedance matching.
