Fixed inductors are an important component in electrical and electronic circuits and can be identified by their self-contained winding. Hong Kong QPE Electronics Co., Ltd. HKQ040220NJ-T is one of the best-sellers in its line of fixed inductors. This article will discuss the application field and working principle of .HKQ040220NJ-T fixed inductors.

1.Application Field of HKQ040220NJ-T

The application field of HKQ040220NJ-T fixed inductors varies depending on the size and type of circuit in which it is used. Generally, they are used for power filtering, high temperature filtering, power regulation and current smoothing. This fixed inductor is primarily used in power supply systems, power amplifiers, and computer circuit boards. It can also be used in auto-start circuits, AC-DC converters, DC-DC converters, LED lighting, Uninterruptable Power Supply (UPS), and other electronic circuits.

2.Working Principle of HKQ040220NJ-T

The HKQ040220NJ-T fixed inductor works using an electromagnetic field. It works by creating an electromotive force (EMF) within a conductor either through a relative motion between it and an external magnetic field or due to a current passing through a wire in a magnetic field or a circuit with multiple windings, like in a transformer. When a current is applied, a voltage is induced by the electromotive force at the opposite ends of the conductor or windings. This induced EMF is determined by the strength of the external magnetic field and the speed of the relative motion, or the amount of current flowing in the conductor.

When the current flows into or out of the coil, it creates a magnetic field that works to reduce or oppose the current passing through it. This acts like an electrical resistor and is known as the inductor’s “inductance”. The inductance of the HKQ040220NJ-T is very high, making it ideal for applications where a large amount of current needs to be filtered. The current flow is limited by the reactive resistance of the HKQ040220NJ-T. The higher the applied voltage across the inductor, the greater the current flow will be.

Conclusion

HKQ040220NJ-T is an excellent choice for power filtering applications, high temperature filtering, power regulation and current smoothing. Its very high inductance makes it ideal for use in these difficult applications. Its working principle is based on the creation of an electromotive force within a conductor by either a relative motion between it and an external magnetic field or due to a current passing through a wire in a magnetic field or a circuit with multiple windings. Its reactive resistance limits the current flow through the inductor, allowing for the efficient filtering of large amounts of current.
