Fixed inductors are an important component of electronic circuits, consisting of a coil of wire and a core made of a ferrous material such as iron. These inductors are used in a variety of applications, from filters and smoothing circuits to RF transmission and reception. The 1210R-822H is a popular fixed inductor, widely used in low and high power applications. This article will explain the application field and working principle of the 1210R-822H.

The 1210R-822H is a fixed inductor that offers very good performance and highly reliable operation in a convenient surface mount package. It is designed with an iron dust core material and electroplated copper wire for improved efficiency and reduced power loss. It features an 11mOhm DC resistance and a 20uH inductance value at 100kHz. In addition, this inductor has a very low self-resonance frequency of only 1MHz, making it ideal for high-speed switching applications.

The primary application field for the 1210R-822H is in high-speed switching applications where its low resistance and relatively high inductance values offer superior performance. It is also often used in smoothing or filtering circuits, providing better control of current flow and higher efficiency. Additionally, this inductor is very popular in radio frequency (RF) circuits, where its low self-resonance frequency can help to reduce noise and improve signal fidelity.

The working principle of the 1210R-822H follows the same general principles as other types of fixed inductors. When a current is applied to the inductor, a magnetic field is created within the inductor coil, which stores energy. When the current is removed, this magnetic field collapses, inducing a voltage which can be used to power other components in the circuit. This phenomenon is known as inductive reactance, and the voltage generated by a fixed inductor is proportional to its inductance.

The 1210R-822H is a highly reliable and efficient fixed inductor with excellent performance characteristics. Its low resistance and high inductance values are ideal for high-speed switching applications, while its low self-resonance frequency makes it suitable for use in radio frequency (RF) circuits. With its robust construction and reliable operation, the 1210R-822H is an ideal choice for a variety of applications.
