Introduction

Fixed inductors, also known as chokes, consist of a coil of wire wrapped around a magnetic core, which usually contains a ferrite material. The main purpose of the core is to create a magnetic field as current passes through the wire coil. This increases the inductance of the coil and the number of turns in the wire. The IHD3EB272L is a type of fixed inductor with applications in a variety of electronic circuits. This article will explore its application field and working principle.

Applications

Fixed inductors are most commonly used in switching power supplies, filters, and other low-frequency analog circuits. The IHD3EB272L is a common choice for these applications due to its excellent performance characteristics. It has low DC resistance and high inductance, which makes it suitable for use in a wide range of frequencies. It is also highly resistant to temperature, vibration, and shock, making it suitable for military and automotive applications. Additionally, the IHD3EB272L is capable of carrying currents up to 5A and has low loss at high frequencies. It can also be used as an adjustable inductor by replacing the core with a ferrite material.

Working Principle

The key element of an inductor is the core, which creates a magnetic field when excited by a current. The core is usually made of a ferrite material, which has the property of storing energy in the form of a magnetic field when an alternating current is passed through the coil. When current passes through the core, the magnetic field created induces voltage across the inductor. This voltage is known as ‘back-EMF’ and acts as a force opposing the current flow. As a result, the current through the inductor becomes limited, thus creating an immovable (fixed) amount of inductance. The number of turns of wire in the coil also affects the inductance, as it increases when more turns are present.

Conclusion

The IHD3EB272L is a type of fixed inductor with excellent performance characteristics. It is predominantly used in switching power supplies, filters, and other low-frequency analog circuits. The core is usually made of a ferrite material, which creates a magnetic field when excited by a current. This magnetic field induces voltage across the inductor, known as ‘back-EMF’, which limits the current through the inductor and creates an immovable (fixed) amount of inductance. The number of turns of wire in the coil also affects the inductance, as it increases when more turns are present.
