Introduction

Fixed Inductors are components used to store electrical energy in the form of a magnetic field, in order to reduce current, attenuate signals or increase voltage. The most common type of Fixed Inductor is the air-core inductor, which uses an air-interrupt space between the core and the coil. Another type is the ferrite-core inductor, which uses a ferrite material to provide a higher inductance than the air-core inductor. The LK1005R82M-TV is a fixed inductor with a ferrite core, designed for use in frequency converters, automotive power electronics, non-contact power transmission systems, and waveform circuit design.

LK1005R82M-TV Working Principle

The LK1005R82M-TV is an air-core inductor, meaning that it doesn’t have a ferrite core. It uses an air-interrupt space between the core and the coil, which is filled with an electrically insulating material such as mica or ceramic. This air gap creates a large inductance in the coil, which makes it ideal for use in high frequency circuit designs.When electrical energy is applied to the coil, it sets up a magnetic field. This energy is then stored in the magnetic field and remains there until it is needed. This inductor can then be used to reduce the current, increase voltage, or attenuate signals.The LK1005R82M-TV is designed to handle high current levels with low EMI interference. It also has a wide temperature range, making it suitable for high-temperature environments. Additionally, its low cost makes it an ideal choice for applications where budget is a major constraint.
