Fixed inductors are electronic components that predominantly store energy in the form of an electric current. The LD1-100-R is a fixed inductor designed for high frequencies and useful in many applications. This article will look into how the device works and provide an overview of its specifications and applications.

Introduction

The LD1-100-R is a non-potted radial fixed inductor designed for high frequency applications. It consists of a ferrite core wound with copper wire. The LD1-100-R has an inductance value of 100nH +- 20%. This device is suitable for frequencies of up to 4MHz for purposes such as RF matching, broadband impedance matching, high-frequency filtering, and pulse shapings.

Working Principle

Fixed inductors, such as the LD1-100-R, rely on magnetism to store energy in the form of a magnetic field. The core is made of ferrite, which is a material that is easily magnetized and demagnetized. This material, along with the number of turns in the coil, determines the inductance of the inductor. When a current is passed through the coil, a magnetic field is created, and energy is stored.

When alternating current is used, which is the case with the LD1-100-R, the magnetic field and the current change direction at each phase of the AC cycle. This flux change, then, induces a voltage in the winding of the coil, creating a reactance that opposes the current. This Reactance, also known as inductive reactance is a measure of how much an inductor resists the flow of current. The value of inductive reactance L is calculated using the following equation:

L = 2 * pi * f * L

Where f is the frequency of the AC signal and L is the inductance of the inductor.
