Fixed Inductors

Inductors are components that store energy in the form of a magnetic field. They provide an inductive reactance, which can be used in a range of circuits and applications to block or regulate the flow of electrical currents. An inductor features a coil of wire which will store current in the form of a magnetic field. Fixed inductors are specific inductors which have a fixed inductance, meaning the inductance of the inductor does not change in response to external factors.The HKQ04023N0S-T is an example of a fixed inductor from EPCOS, a leading manufacturer of power components such as Thyristors, Diodes and IGBTs. The HKQ04023N0S-T has a variety of applications and comes in a compact, convenient surface mount package that requires minimal board space for mounting.The HKQ04023N0S-T is a power inductor from EPCOS that provides consistent capacitance due to its low temperature coefficient. The HKQ04023N0S-T features a high inductance value, along with a low DC resistance and high self-resonant frequency. This makes it suitable for digital camera modules, mobile device switched mode power supplies as well as fast switching power supplies.In terms of the HKQ04023N0S-T\'s working principle, it functions through the process of electromagnetism, where an electric current through a wire coil creates a magnetic field around the coil. This magnetic field is influenced by the wire, the length of the wire and the number of coils, or turns, in the wire. This means that a change in the current will cause a change in the magnetic field, and as a result an opposing voltage is produced, known as the back voltage. This opposing voltage can be used to regulate the current and voltage in certain applications.The HKQ04023N0S-T is a fixed inductor with a high operating temperature of 135°C, and a wide capability range that ranges from 10µH to 3.9mH and above. It is also able to maintain inductance values over a large range of frequencies, and supports a variety of stability conditions. The HKQ04023N0S-T also contains a fully automated mounting process, meaning minimal installation time is needed and it is efficient to use in places where space and time are of the essence.Overall, the HKQ04023N0S-T fixed inductor is a great solution for a variety of power supply applications, thanks to its impressive performance in terms of stability, temperature coefficient and high operating temperature. The wide range of applications it supports is also an added bonus, and its compact package makes it suitable for industrial and commercial use.
