An Introduction to the HKQ040210NJ-E

The HKQ040210NJ-E is a fixed inductor, which has a variety of applications and a novel working principle. This article will discuss the various parts of the device, including its design, application field, and working principle.

Design

The HKQ040210NJ-E is a triple-layer surface-mount device designed for reliable on-board mounting. It is composed of two molded ferrite core inductors, which are then squeezed together to form a flat, square surface. The core inductors are made of low resistance and high permeability ceramic body material. The device also includes a layer of copper foil winding to promote conduction. The two winding layers of copper foil are separated by two polypropylene film layers, and these layers ensure that electric current is not able to flow between the two core inductors.

Application Field

The HKQ040210NJ-E is primarily used in circuit applications to reduce electrical interference. It is particularly useful for applications in audio devices, medical instruments, and telecommunication systems. The device is resistant to vibration, and it has a good self-healing ability due to its polypropylene film layers. In addition, it is able to reduce the voltage between parts in a circuit, and it can also be used to filter high-frequency signals. Furthermore, the device has a low-profile design, allowing for easy portability and placement.

Working Principle

The HKQ040210NJ-E works by storing and then releasing energy in a magnetic field. When current passes through the device, a magnetic field is generated which stores energy in its inductor cores. When the current flow stops, the stored energy is released in the form of a voltage spike. This voltage spike helps regulate the voltage between parts in the circuit, thus reducing the amount of electrical interference. In addition to this, the device is able to filter out high-frequency signals due to its two layers of copper foil winding.

Conclusion

The HKQ040210NJ-E is a fixed inductor, which has a variety of applications and a novel working principle. With its low resistance and high permeability ceramic body material, polypropylene film layers, and copper foil winding, the device is able to reduce electrical interference and filter high-frequency signals. This makes the HKQ040210NJ-E an ideal choice for a variety of applications, including audio devices, medical instruments, and telecommunication systems.
