Fixed Inductors

Inductors are fundamental components of electronic circuits and are used in a wide range of applications. Fixed inductors are among the simplest types of components, and are widely used in electrical circuits and systems. The IR02SHR22K is a type of fixed inductor developed by Infineon Technologies. This article will discuss the application field and working principle of the IR02SHR22K.

General Description of the IR02SHR22K

The IR02SHR22K is a fixed inductor developed by Infineon Technologies. It has a rated inductance of 0.275 mH ±20%, a self-resonant frequency of 27.3 MHz, and a Saturation Current of 15.6 A. The IR02SHR22K is designed to be operated in a temperature range of -40 to +85°C. It is also designed to be compatible with up to 1000V AC/DC.

Application Field of the IR02SHR22K

The IR02SHR22K is used in a wide range of applications. These include power supplies, power converters, dc-dc converters, current mode control circuits, and AC circuit filters. The IR02SHR22K is especially useful in applications that require high current and high power. The high current rating and low profile of the IR02SHR22K makes it ideal for use in tight spaces where other components may not fit.

The IR02SHR22K is also used in high frequency, high power applications and is commonly used in cellular base stations, PLCs, and other communication systems. It is also used in automotive applications, such as for the control of air bags, seat belt tensioners, automotive lighting, and electric motors.

Working Principle of the IR02SHR22K

The IR02SHR22K fixed inductor works on the same basic principles as other inductors. When electric current flows through the coil of the inductor, an induced magnetic field is generated. This magnetic field stores energy in the form of magnetic flux. This stored energy is known as inductance. The larger the inductance of an inductor, the greater the amount of magnetic flux it can store and the higher the quality factor of the inductor.

The IR02SHR22K utilizes this principle to regulate current in the circuit and ensure the desired voltage levels are maintained. The inductor helps to reduce the rate of change of current in the circuit by increasing the magnetic resistance of the inductor. This is known as inductive reactance and it limits the flow of current. The inductor also contributes to filter the input signal when necessary, acting as a high pass filter by blocking any low frequency signals.

In summary, the IR02SHR22K is a versatile fixed inductor suitable for a wide range of applications. This inductor is designed to provide reliable current regulation and filtering in high power, high frequency applications. It has a high current rating, low profile, and high quality factor, making it an optimal choice for applications where space is limited and superior performance is desired.
