Introduction to Fixed Inductors

Fixed inductors are a type of passive electrical component used to store electrical energy in the form of a magnetic field. They are commonly found in circuits, especially high-frequency circuits, and are a fundamental part of many electronics and electrical circuits.

1210-222H Application Field and Working Principle

The 1210-222H is a surface-mount fixed inductor with a ferrite core and molded electroplated terminals. It has an inductance of 2.2 µH and a maximum DC current of 0.6A. The 1210-222H can be used in a wide variety of applications, including power supplies, SMPS, and DC/DC converters.The 1210-222H works via Faraday\'s law of induction, which states that the induced voltage in a circuit is directly proportional to the rate of change of the magnetic flux. This means that when a varying current passes through the inductor, it will create a varying magnetic field, inducing a voltage. The voltage induced is inversely proportional to the inductance of the inductor. Therefore, the 1210-222H has an inductance of 2.2 µH, so it will induce a relatively small voltage.

Conclusion

The 1210-222H is a fixed inductor with a ferrite core and molded electroplated terminals. It is suitable for a variety of applications, such as power supplies, SMPS, and DC/DC converters. This type of inductor works according to Faraday\'s law of induction, which states that the rate of change of magnetic flux induces a voltage in the circuit, with the induced voltage being inversely proportional to the inductance. This means that the 1210-222H will induce a relatively small voltage due to its 2.2 µH inductance.
