Fixed Inductors Overview

Inductors are passive electronic components designed to store energy in the form of a magnetic field. They are used for various electrical and electronic applications, such as filtering, voltage-flow regulation, signal transmission, and generation of signals. Fixed inductors (also known as discrete, choke, or reactive components) are electrical components in which the inductance value remains constant in wide normal operating conditions. They are perfect for applications which require a precise, consistent, and repeatable inductance value.Fixed inductors are classified into two types based on the core material they use – air-core and ferrite core. Of these, air-core inductors typically provide higher accuracy inductance but the lower inductance values they provide are not suited for high current applications. On the other hand, ferrite core inductors are suitable for high current applications but do not provide the higher accuracy inductance.

ELL-3GM1R0N Application Field and Working Principle

The ELL-3GM1R0N is a fixed inductor designed for high current applications. It is constructed with a two-layer molded package using Temperature coefficient of inductance (TCL) Organic-polymer substrate (OPS) technology. This fixed inductor operates over a wide temperature range (-20℃ to120℃). This component provides high-stability, high-reliability, and excellent electro-magnetic interference (EMI) blocking. The ELL-3GM1R0N inductor also features a small footprint, low profile design. Its dimensions are 8.4 mm x 8.2 mm x 10.0 mm. It has soldering mounting pads so it can easily be soldered to a PCB.The working principle of the ELL-3GM1R0N fixed inductor is based on the generation of a magnetic field when a current is passed through its terminals. The magnetic field, in turn, induces a voltage across the inductor. The induction created by the coil restricts the flow of current across it. At high frequency, the inductance and capacitance of the component combine to form a low-pass filter. The ELL-3GM1R0N fixed inductor features an inductance value of 2.2uH +/- 30%. It has a rated current up to 4.2A (max). It ships with an insulation resistance of greater than 10 kOhm and a rated DC resistance of 1.6 Ohms. This fixed inductor has a maximum hostile load of 1500 KHz and an inductance drift of -0.62 %/K (typ).
