Fixed Inductors are important components in various electronic appliances. They are widely used in AC/DC conversion, current filter, signal filter, and transformer and other occasions. HKQ04022N6S-T is a type of fixed inductor. This article will focus on its application field and working principle.

HKQ04022N6S-T fixed inductors are generally made of ferrite and can adopt various shapes. Its inductance value is between 0.15μH and 4.7mH. It is used in power supply conversion and filtering, and can also perform EMI function. This component is usually used with solid capacitors, chip capacitors and resistors to form a filtering circuit.

The working principle of the HKQ04022N6S-T fixed inductor is based on the principle of the electromagnetic induction. When a sinusoidal voltage is applied between its two terminals, an induced current is generated in the inductor. It acts as a low pass filter, that is, it only allows the low frequency current to pass and blocks the high frequency current.

This component is mainly used in electronic circuits with high frequency and high current occasions, such as power conversion circuit, RF signal circuit, battery banks, electrodes and communication antenna. In power conversion, an inductor can reduce the switching noise of high frequency pulse signal and reduce the output current ripple, which helps to improve the conversion efficiency. In the communication antenna, an inductor is used as an inductive tuning component to match the impedance. And it can also prevent RF signal from interfering with other circuits.

In addition, the HKQ04022N6S-T fixed inductor can also be used in the output filter of the power amplifier. Because inductors and capacitors can form a resonance point at certain frequency, at this frequency, the attenuation rate of the signal is highest, so that the high frequency signal can be effectively eliminated.

The HKQ04022N6S-T fixed inductor plays a vital role in various electronic appliances, and its application field and working principle described herein will help us to better understand its usage and performance.
