Fixed Inductors

A fixed inductor is an electrical component which stores and releases energy in the form of an electric current or a magnetic flux. It is made of coils of insulated wire and is sometimes used in conjunction with a capacitor to form an RC circuit. Fixed inductors can be used to generate sinusoidal voltages, filter radio-frequency signals, match impedance in electrical circuits, and act as circuit elements in radio receivers. One specific type of fixed inductor is the 5022-182H.

5022-182H Application Fields

The 5022-182H is commonly used in electronics such as audio amplifiers, audio mixers, and power supplies. It is also used as an RF filter for circuits which require high-efficiency attenuation of frequencies within a certain range. It is often used in RFID (radio-frequency identification) systems, but is not suited for use in very low frequency circuits due to its high impedance.

5022-182H Working Principle

The 5022-182H fixed inductor has a nominal inductance of 0.002H and a maximum current rating of 0.05A. It has a very low DCR (direct current resistance) and high Q (quality factor). Generally, when current flows through the coil of the inductor it produces a magnetic field which resists changes in the current. This effect is known as inductance. The inductor can store this energy and use it to oppose a change in the input voltage. This means that when voltage is applied across the terminals of the inductor the output current lags the input voltage.

Conclusion

The 5022-182H fixed inductor is a widely used component in a variety of electronic devices. Its high-efficiency attenuation is ideal for RFID systems and its low DCR and high Q factor make it suitable for a wide range of audio applications. Its working principle is based on the storing of energy in the form of an electric current or a magnetic flux in order to oppose changes in the input voltage.
