Fixed inductors, also referred as "fixed-value inductors", are permanent magnet (PM) devices with a minimum number of winding layers that cannot vary their inductance value. The IHB4BV221K is an example of a common fixed inductor used in many applications.

The IHB4BV221K fixed inductor has a maximum DC resistance of 8.7 ohms, and an inductance value of 33uH. This is a very useful inductor in many applications due to its wide operating temperature range of between –40°C and +85°C. Its high reliability and excellent electromagnetic compatibility (EMC) make it a suitable choice for many applications.

The IHB4BV221K is most commonly used in power supplies, particularly those that will require a high degree of electrical isolation and high-performance characteristics. It is well-suited for applications that require a wide band of load regulation and transient response. Common examples include dc-to-dc converters, power supplies, power inverters, and AC-to-DC converters. It is also frequently used in precision electronic filter circuits in a variety of analog and digital audio systems.

The IHB4BV221K has a simple working principle. The core of the device is made from ferrite, and the two leads are usually inserted into opposite ends of the core. A conductive winding composed of copper wire is wound around the core. When current passes through the winding, a magnetic field is created. This magnetic field interacts with the core material, creating an inductance or delay in the current flowing through the device. By varying the number of turns and the size of the core material, the inductance and electrical isolation of the device can be controlled.

The IHB4BV221K is a high-performance fixed inductor with excellent reliability and EMC properties. It can be used in a wide variety of applications and is well-suited for power supply applications, especially those that require high electrical isolation and load regulation. Its simple working principle makes it a reliable and cost-effective solution for many inductor-based designs.
