Fixed Inductors

IR02SHR18K application field and working principle

A fixed inductor, such as the IR02SHR18K, is an electronic device that stores energy in a magnetic field when current flows through it. This energy can either be used directly or stored and released at a later time. The IR02SHR18K is a surface-mount multilayer chip inductor. It is designed for high current density applications and is suitable for use in a wide variety of electronic systems.

Application fields

Fixed inductors, such as the IR02SHR18K, are commonly found in telecommunications and networking, automotive, military, and consumer electronics fields. In telecommunications industries, they are typically used as part of a radio frequency filtering circuit. They are also used in transformer circuits, where a high current density and stable hashed inductance is required. In automotive and military electronics, they are typically used as part of a circuit that is used to power electromagnetic actuators. In consumer electronics, they are commonly used in switching power supplies, as filters, and as part of audio circuit designs.

Working principle

The IR02SHR18K is a passive component that stores energy in a magnetic field created by the flow of current through it. The inductor is made up of a coil of wire that is surrounded by a magnetic core material. The core material can be made of ferrite, air, or powdered iron. When an electric current flows through the coil it generates a magnetic field. The magnetic field stores energy and creates an opposing voltage and electric current as the magnetic field collapses. The voltage and current generated depend on the inductance of the circuit, and can be used to filter out or smooth out voltage and current spikes.

The IR02SHR18K utilizes a ferrite magnetic core material, which allows it to have a higher current capacity and inductance than other inductors. It is designed to be used on printed circuit boards, and features a small size and a high thermal capacity.
