Fixed inductors, also referred to as "fixed coils", are inductors whose inductance value remains fixed and does not vary with the frequency. The HKQ040210NH-E is a series of fixed inductors designed mainly for Power Line EMI Filtering applications, although they can also be used for other general purpose applications. These models feature high inductance between 3.3 and 4.7 uH, and come in various sizes for, different applications. This article will discuss the application field and working principles of the HKQ040210NH-E.

Application Field of HKQ040210NH-E

The HKQ040210NH-E is primarily used for power line EMI filtering, but can also be used in general purpose applications. As a power line EMI filter, the HKQ040210NH-E is designed to suppress high frequency electrical noise that is generated by different kinds of equipment, such as computers, electronic circuits, and motors. It reduces the EMI (electromagnetic interference) emitted from these types of equipment in order to protect other equipment from the noise. In addition, the HKQ040210NH-E can also be used in circuit design to reduce the power consumption of circuit components or to dampen the power source to prevent overcurrent. These features make the HKQ040210NH-E an ideal choice for power line EMI filtering.

Working Principles of HKQ040210NH-E

The working principle of the HKQ040210NH-E involves the two basic principles of inductors - self-induction and electromagnetic coupling. When a current is passed through the inductor, a voltage is induced across the winding, which is known as self-induction. This voltage opposes any further current and causes the inductor to resist any changes in the current through it. This is known as inductance. The second principle of inductors, electromagnetic coupling, is the process by which energy is transferred from one inductor to another. The inductors act as coils, transferring energy through a magnetic field between them. This energy transfer happens when the current in each inductor is varied at the same time.

The HKQ040210NH-E series of fixed inductors uses these two principles to reduce the EMI noise generated by equipment and limit the current in circuits. The inductor is placed in the circuit, where it acts as an EMI filter s by blocking high frequency noise and allowing the low frequency noise to pass. Additionally, the inductor also creates a dampening effect on the circuit, limiting the current and preventing the circuit from overloading.

Conclusion

The HKQ040210NH-E series of fixed inductors is an ideal solution for power line EMI filtering applications. The inductors use the two principles of self-induction and electromagnetic coupling to reduce the EMI noise from electric equipment and limit the current in the circuit. The HKQ040210NH-E is a reliable and effective solution for power line EMI filtering needs, making it a great choice for those looking for an efficient and effective way to reduce EMI interference.
