Fixed inductors are a group of electrical components that can store energy in the form of circular magnetic fields. They are particularly useful in producing filtering or tuning functions in electrical circuits. The SRP4012TA-1R2M is a type of fixed inductor manufactured by Sumida Corporation. This inductor is made from a ferrite-core material and is specially designed for use in power-supply filtering applications.

The SRP4012TA-1R2M is designed to provide a low internal resistance while maintaining a relatively high inductance value of 1.2mH. It has a rated DC current of 2.2A and its DC resistance is around 0.26 Ω. The inductor has a rated self-resonant frequency of 6MHz and is capable of maintaining a good inductance stability over a wide range of temperatures, thus making it suitable for use in a number of different applications.

The SRP4012TA-1R2M is well-suited for use in various power supply filtering applications. Its low DC resistance makes it ideal for use in switching power supplies as it reduces the switching time of power supplies while simultaneously reducing the voltage ripple. It is also suitable for use in linear power supplies to reduce the current noises which can reduce the required power rating of these supplies. It is also often used in voltage regulators, DC/DC converters, and other related power-conversion applications.

The working principle of a fixed inductor is based on the principle of electromagnetic induction. This principle states that when an electric current is flowing through a wire, a circular magnetic field is created around it. This circular magnetic field induces an electromotive force in a second wire which is linked to the first wire. The resulting current in the secondary circuit is directly proportional to the rate of change of current in the primary circuit.

The SRP4012TA-1R2M is a fixed inductor that uses this principle of electromagnetic induction to store energy in the form of a circular magnetic field. The SRP4012TA-1R2M stores energy at a rate determined by its characteristics. The inductor is designed to have low DC resistance yet maintain a relatively high inductance value. This, combined with its good temperature stability, makes it suitable for a number of power-supply filtering applications.
