Fixed Inductors

The HKQ04025N1H-T is an example of a fixed inductor. Fixed inductors are electrical components that store energy through the creation of a magnetic field in a wire coil. This device has many application fields and is designed for many different situations, from switching power supplies to common DC-DC converters. This particular device is a surface-mount device with high reliability and low temperature coefficient.

Application Fields

The HKQ04025N1H-T can be used in a wide variety of applications. It is commonly used in switching power supplies, which are used in cameras, CD players, DVD players, etc., for providing and regulating direct current voltages in various applications. It can also be used as a filter inductor in existing DC-DC converters, or as an output filter inductor in new DC-DC converter designs. The HKQ04025N1H-T is also suitable for AC line filter applications, such as in LCD TVs and monitors.

Working Principle

An inductor works by creating a magnetic field in a wire coil in response to the passage of electrical current. The resulting effect is to store energy in the form of a magnetic field, which can be converted back into electrical energy when needed. The amount of energy stored is determined by the number of turns in the coil and the magnitude of the current passing through it. The inductor is said to “react” to changes in the current, as the magnetic field generated by the coil opposes the change in current.

The HKQ04025N1H-T is a high reliability inductor with a low temperature coefficient, and is suitable for operation over a wide temperature range. It features a shield core construction, with a single-turn wire, enabling easier and cheaper assembly. Its design ensures the creation of a strong and stable magnetic field in response to the currents passing through it.

Conclusion

Fixed inductors, such as the HKQ04025N1H-T, are devices designed for storing electrical energy through the creation of a magnetic field in coils of wire. These components have a wide range of applications, from switching power supplies to DC-DC converters, and are characterized by low temperature coefficient and high reliability. The working principle of an inductor involves the generation of a magnetic field in the coil, which opposes changes in current, thus storing energy and enabling its conversion back into electrical energy when needed.
