Fixed Inductors

Fixed inductors, also called coils, are electronic components used in most electronic circuits to induce electrical current or voltage. They use magnetic fields to perform their function and are used to store electrical energy, filter noise or create a resonant frequency. Fixed inductors are used in a wide range of applications, including radio and communications equipment, medical equipment and consumer electronics.

LQH31MN390K03L Application Field and Working Principle

LQH31MN390K03L is a special type of fixed inductor manufactured by TOKIN. This series is an SMD chip inductor mainly used in mobile electronics. It is compact, versatile and reliable in design, making it ideal for various applications.

The LQH31MN390K03L is suitable for a wide variety of applications. It is particularly useful for high frequency applications such as noise filtering, signal limiting and demodulation, rectification, pulse shaping, power conversion and rate controlling. Additionally, it is well suited for DC-DC converters, SMPS, telecom and audio applications.

Under normal circumstances, the LQH31MN390K03L works by inducting a current when subjected to a changing current (alternating current) in an active circuit. When an AC current passes through a coil wrapped around a core, a magnetic field is created. This magnetic field induces an electric current in the coil. This is known as induction. This induced current can be used to trigger an effect, such as powering a circuit, amplifying a signal, or filtering noise.

The LQH31MN390K03L is small but powerful—despite its miniature size, it can handle up to 1.45Amps (50V). It has a winding demagnetization rate of 15% maximized, making it highly reliable. Additionally, its efficient construction minimizes power loss and noise generation.

Conclusion

The LQH31MN390K03L fixed inductor is an effective and reliable component that is suitable for a wide range of applications. It utilizes inductance to induce a current or voltage when subjected to an alternating current in an active circuit. Its compact size and high performance make it a go-to choice for many electronics-related applications.
