Fixed inductors are electrical components that are designed to protect and store electrical energy in electrical systems. IM02SHR82K is one of the most commonly used inductive components in this industry. This article will discuss the application field and working principle of the IM02SHR82K.

Application Field

The IM02SHR82K is a high-performance, surface-mount inductor with a wide range of applications in power supply circuits, DC-DC converters, signal decoupling networks, and other kinds of switching power supplies. It is also widely used in the drawing force, iron core transformer, wave trap, low-frequency pulse transformer, etc. The most common application of this device is in switch-mode power supplies, which are devices that use pulse-width modulation to convert AC to DC power.

The IM02SHR82K is designed with a high degree of efficiency and reliability, making it a versatile, cost-effective choice for various applications. It has an excellent peak current rating of 2.2A and a saturation current of 2A, enabling it to support a wide range of switching frequencies. Additionally, its surface-mount design allows for easy PCB implementation and minimizes board space.

Working Principle

The working principle of the IM02SHR82K is based on the fundamental concept of inductance in electrical circuits. In a typical electrical circuit, an inductor resists the change in current, creating a voltage drop when current passes through it. The IM02SHR82K is designed with a tightly wound coil which can resist the flow of high-frequency currents, effectively acting as a filter. This type of inductor is usually used in switch-mode power supplies, where the inductor acts as a low-pass filter filter that reduce noise and high-frequency interference on the input and output lines.

The working principle of the IM02SHR82K is also based on the principles of inductive reactance and magnetic flux. Inductive reactance is the resistance to the flow of alternating current due to the inductance in the circuit. Magnetic flux, on the other hand, refers to the flow of magnetic energy in a magnetic field. The IM02SHR82K is designed with a tightly wound coil that creates an air gap in the magnetic core, which yields a higher inductance than if the core was left solid. This higher inductance increases the reactance of the device, making it more effective in filtering high-frequency currents.

Conclusion

The IM02SHR82K is a widely used surface-mount powered inductor that is cost-effective and reliable. It has an excellent peak current rating of 2.2A and a relatively high saturation current of 2A, making it a versatile choice for various switching power supplies. The working principle of the IM02SHR82K is based on the principles of inductive reactance and magnetic flux. It is designed with a tightly wound coil that creates an air gap in the magnetic core, which yields a higher inductance than if the core was left solid. This higher inductance increases the reactance of the device, making it more effective in filtering high-frequency currents.
