HKQ04021N4S-T

Fixed inductors are electrical components that store energy in the form of a magnetic field. They are passive two-terminal components commonly used in electrical circuits to add inductance or perform filtering and rectification. HKQ04021N4S-T is a fixed inductor produced by Tianshui Huike Electronics Co., Ltd, introducing its application field and working principle.

Applications for the HKQ04021N4S-T Fixed Inductor

HKQ04021N4S-T fixed inductors are suitable for switch-mode power supplies, for power from 10W to 15W. It is also commonly used in HID lamps, automotive LCD backlights, and CFL lamps. The inductor carries an insulation class of F, meaning that it can withstand withstand a temperature of up to 160℃ without any risk of overheat. With a typical resistance value of 0.08Ω, this inductor has a low DCR, making it the perfect choice for different power applications.

Working principle of the HKQ04021N4S-T Fixed Inductor

HKQ04021N4S-T fixed inductors use a ferrite core to store energy in the form of a magnetic field. When a current passes through the inductor, power is received from the source and stored in a form of an AC magnetic field in the ferrite core. This field will store the energy until it gradually decreases, at which point the inductor will convert magnetic field energy back into electric energy and return it to the source. This process helps prevent power surges, filter rectified AC power, and reduce the amount of noise in the circuit.

In order to obtain the greatest efficiency from the inductor and ensure that its operation is unaffected by vibrations, it must be properly mounted on the desired platform. The manufacturer suggests that the part be mounted using standard mounting screw holes and a heat resistant clip between 0.5mm and 0.7mm thick. This will ensure proper heat dissipation, minimise potential losses, and guarantee safe operation.

The HKQ04021N4S-T fixed inductor is a reliable and cost-effective component, offering excellent electrical characteristics. It is suitable for applications requiring efficient inductors, including switch-mode power supplies, HID lamps, CFL lamps, and automotive LCD backlights.
