Fixed Inductors

A fixed inductor, also known as a permanent magnet or just simply an inductor, is an electronic component that stores electrical energy in a magnetic field. When an alternating current is applied to the inductor, the magnetic field stores the energy and then it will be released into the circuit as soon as the current is removed. The inductance of an inductor is directly proportional to the number of turns of wire used in the coil and the amount of current flowing through the circuit.

IHB4BV271K Application Field and Working Principle

IHB4BV271K is a fixed single-layer rectangular coil inductor that is made of ferrite material, and it is mostly used in power circuits. It is constructed with two anodized windings on a ferrite core and its winding height can be adjusted from 0.9mm to 1.5mm. Equipped with a range of inductance from 0.9mH to 270mH, the IHB4BV271K inductors offer excellent electrical parameters with high power, low resistance, excellent thermal shock characteristics and excellent long-term stability.

The working principle of IHB4BV271K relies on the transformer action of the applied current, which induces a voltage to produce a magnetic field by setting up an oscillation relationship between two windings. The core material, such as ferrite, works as the vehicle that concentrates the field and to control its size and shape. Due to the magnetic field generated by the core material, the inductance value is created. Thus, the inductance of IHB4BV271K inductor is proportional to the number of turns of wire in the coil, the core material and the current flowing through the circuit.

Additional features that make IHB4BV271K inductors attractive for use in power circuits include their small size, reliable performance, higher power ratings, and excellent thermal dissipation. Since this type of inductor is mostly used in power applications, having low resistance, high power ratings, excellent thermal dissipation, and high stability are essential to safe operation.

IHB4BV271K is not a high frequency inductance, and its use is generally limited to the power range of 44.0uH ~ 270.0uH and the rated current range of 0.14A ~ 0.56A. Furthermore, the temperature range of IHB4BV271K inductors is -40°C~+125°C. Even with a temperature that is already low by power ratings standards, IHB4BV271K was tested to have good thermal shock performance.

In conclusion, IHB4BV271K is an ideal choice for a range of applications from audio systems to power circuits, due to its excellent electrical parameters and temperature range. Furthermore, its reliable performance, high power ratings, and excellent thermal dissipation make it an ideal inductor for any application in power circuits.
