Fixed Inductors

Fixed inductors, also sometimes known as adjustable or variable inductors, are electronic components that use an electrode (typically a wire) wrapped around a ferrite core, which reduces the inductor’s resistance when current is applied. Fixed inductors are usually used to adjust the resonant frequency of electrical circuits. The 0925R-153K is a fixed inductor that features low values of resistance along with high values of inductance and peak currents.

Application Field

The application field of the 0925R-153K fixed inductor is in the production of switched-mode power supplies (SMPS), power circuits used to step-down voltage levels. It can also be used to form part of a voltage regulator circuit, and can be used with low-voltage integrated circuits (ICs) in these devices. Furthermore, the 0925R-153K is useful in the construction of filters, for applications such as the separation of radio frequencies for antenna applications.

Working Principle

The working principle of the 0925R-153K is such that the inductor increases the current in the electrical circuit when there is a change in the voltage, and vice versa. When an electrical current passes through the wire electrode, the magnetic field produced by the inductor induces a back current due to Faraday’s law, which increases the inductance of the core. This increases the inductor’s resistance when current is applied, and decreases it when the current is reduced.

The 0925R-153K is one of the most common types of fixed inductors, and due to its efficacy, it can be used in a range of applications. With its low values of resistance along with the high values of inductance and peak currents, this inductor is a popular choice amongst designers.
