Fixed Inductors – 1210R-472G Application Field and Working PrincipleFixed inductors are widely used in various electronic circuits, including power supplies, digital timing, and signal and modulation processing. In particular, inductors are the key components of circuits in the power system, and they also act as filters to reduce distortion and noise. One particular type of inductor is the 1210R-472G fixed inductor, which is widely used in power and signal processing applications. This article outlines the characteristics of the 1210R-472G inductor, its application field and working principle. The 1210R-472G is a surface mount fixed inductor that is made of metal oxide core material and is characterized by excellent inductance stability in temperature change. It has a magnetic core that is made of metal oxide and epoxy resin. This combination of materials makes the inductor highly reliable and provides excellent cost to performance ratio. The 1210R-472G has a maximum inductance range of 0.47 uH, a maximum DC current of 1.25A and a ripple current of 0.15A. It is also equipped with built-in EMI filtering capabilities. The 1210R-472G fixed inductor is used in a wide range of applications, including AC and DC power supplies, filtering components, signal couplers, transformers and switches. It is also used in high-power circuits such as power transformers and power supplies. Moreover, the 1210R-472G is used in regulating circuits, signal conditioning, transistors, transceivers, amplifiers, radio signals, memory circuits and the like.The working principle of the 1210R-472G inductor is based on Faraday’s Law of Induction. When an electric current flows through the coil, a magnetic field is created around it that is proportional to the current flowing through it. This field induces an electromotive force, or voltage, in the coil. This voltage, in turn, creates a current in the coil, which is proportional to the induced voltage in the coil. This is known as self-induction. The continuous flow of electric current through the coil of the 1210R-472G produces a continuous magnetic field around it, reflected by the constant voltage across its terminals.The 1210R-472G fixed inductor is highly reliable and cost-effective, and it is suitable for high-power applications. Moreover, it provides excellent inductance stability and provides built-in EMI filtering capabilities. This makes it an ideal component for power and signal processing applications.
