Fixed Inductors: HKQ04022N3C-T

Fixed inductors, also known as “chokes”, are components of a circuit designed to store energy using a magnetic field. They are used to limit current, eliminate voltage spikes, and filter objectionable noise from otherwise steady signals. In this article we\'ll look specifically at the HKQ04022N3C-T fixed inductor, explore its application field and explain its working principle.

Application Field

HKQ04022N3C-T fixed inductors are small surface-mount components primarily used to filter out high-frequency noise on consumer and industrial devices. Because of its low thermal resistance, it can handle power loads efficiently and dissipate heat quickly. This makes it ideal for high-power circuitry in a small amount of space.

Its wide applications span a variety of areas, from communication processors, portable digital products, automotive systems, to PC- and laptop-related products. Threaded from 1.25A to 5A, it has a variety of shapes to fit many industry needs.

Working Principle

The HKQ04022N3C-T fixed inductor uses a high-quality ferrite core, combined with precision winding and special shielding techniques, to store energy as a magnetic field. When an alternating current is passed through the winding, it creates a continuous electromagnetic field, in turn creating an inductance. This can control the speed of current flow, and also filter out high-frequency noise.

Because of the ferrite core, the current passing through the coil can be higher than the rated current without saturating the core and causing a burnout. This enables it to offer superior current handling capability and firm inductance even at high current loads.

In addition, due to its shielded structure, the HKQ04022N3C-T fixed inductor offers high shielding effectiveness, low insertion loss, and low torque. This is important for schematic designs that require high performance in a small size.

Conclusion

The HKQ04022N3C-T fixed inductor is a robust, reliable component for high-frequency filtering applications. Its superior current handling capability, small size, and high shielding effect make it an ideal choice for both consumer and industrial systems.
