Introduction

Fixed inductors, also known as fixed coils, are devices for storing energy in the form of a magnetic field and releasing it when subjected to an alternating current. The B82422A1302K100 is a type of fixed inductor that is widely used in power electronics applications. This article will discuss the application field and working principle of the B82422A1302K100.

Application Field

The B82422A1302K100 is well-suited for a variety of power electronics applications, such as high-frequency switching power supplies, DC-DC converters, and power factor correction circuits. As one of the most popular types of fixed inductors, its small size and high energy density make it ideal for use in high-density power electronics products. In addition, the device offers low core-loss and high temperature stability, making it an ideal choice for applications such as computer peripherals, game consoles, and other high-frequency switching power supplies.

Working Principle

The B82422A1302K100 fixed inductor operates based on the principles of electromagnetism. The inductor consists of a coil of wire that is wrapped around a core. When a current passes through the coil, a magnetic field is formed in the core, which stores energy in the form of a magnetic field. When the current is reversed, the core releases the energy, creating a voltage across the coil\'s terminals. This voltage can then be used to power circuits or to store energy for later use.By controlling the core material, inductance of the B82422A1302K100 can be accurately tuned, allowing for precise control of output voltage over a wide range of frequencies. This makes the device ideal for use in precision power electronics applications such as current-mode control, pulse width modulation, and frequency control.In addition, the B82422A1302K100 offers excellent tolerance characteristics for precision control. The device\'s self-resonant frequency allows for accurate resonance control of AC trimming, increasing accuracy and efficiency of power control. It also offers low DC and AC resistance for low power consumption and minimal noise.

Conclusion

In conclusion, the B82422A1302K100 fixed inductor is an ideal component for use in a variety of power electronics applications, due to its small size, high energy density, low core-loss, and high temperature stability. The device\'s precise control characteristics allow for precise control of power delivery and accuracy in current-mode control, pulse width modulation, and frequency control. In addition, its excellent tolerance characteristics enable accurate resonance control of AC trimming, resulting in improved power efficiency.
