Fixed inductors are components of electrical networks which are permanently magnetized with the help of an inductive coil, in order to introduce certain quantities of inductance and impedance into them. The HKQ04021N3B-T is one such device and a popular choice in the field of inductors. It is manufactured by Murata and features a wide range of applications in various industries.

The HKQ04021N3B-T is most commonly used for controlling the EMI noise levels in power cables, as they are able to absorb and disperse the electromagnetic noise generated within the open circuit. The device also works as a filter in communication systems, connecting the signals and providing EMI/RFI protection against electromagnetic disturbances.

The device’s working principle is based on the fact that it consists of a coil of insulated wire. Its inductance is determined by the number of turns in the coil, the diameter of the coil and the core material, such as ferrite, within it. The core material functions to concentrate the magnetic field created by the coil, thereby enhancing the device’s magnetic properties. The device can be used to create a self-resonance frequency, given that the Q factor experienced by the device is high.

Moreover, the HKQ04021N3B-T is a popular choice in audio crossover networks. Here, it can be used as a high-pass filter that eliminates audio frequencies below the crossover point. Such filters are effective in eliminating “boomy” bass effects that are commonly heard in low-quality audio equipment.

The device’s exemplary performance and wide range of features make it the go-to choice for inductors in different applications. Industries such as automotive, telecom, digital, audio, medical, fire-alarm, and other environments also benefit from the use of HKQ04021N3B-T fixed inductors. Moreover, they are extremely cost-effective when compared to other inductors on the market.
