Fixed Inductors

Introduction

A fixed inductor, also referred to as a choke, is a type of electronic device used in many circuits for the storage and control of energy. Chokes belong to the family of passive components, which means they do not require any external power to function. This makes them an essential component in most devices and can be found in many electronics, from computers to cell phones.

UP0.4UC-471-R Application Field and Working Principle

The UP0.4UC-471-R fixed inductor is a non-polarised device with a wire-wound ferrite core, suitable for applications with an operating frequency of up to 100kHz. The inductor has a low-profile, sealed design, making it ideal for high temperature environments. It has excellent high frequency performance, with a self-inductance of 4.71uH and a DC resistance of 0.206Ω. The UP0.4UC-471-R also features high current ratings of 1.2A and low ESR of 0.075Ω, making it a reliable choice for DC-DC converters.

When used in a circuit, the UP0.4UC-471-R fixed inductor acts as a filter to limit the flow of current. It works similarly to a resistor, but instead of reducing the current, it limits the rate of current change. This is known as inductance and it can be used to reduce the noise in a circuit. It also provides additional filtering of AC and DC signals. The UP0.4UC-471-R also has a magnetic field produced by the core which can be harnessed in certain applications.
