Fixed Inductors are devices composed of windings of wire, with or without insulation, surrounding a core of ferromagnetic material.

The SRU1038A-221Y is a through hole fixed inductor, with an inductance range of 2.4mH to 39.2mH. The nominal inductance of this device is 28.9mH. It is rated for currents up to 4.5A, and for an operating temperature range of -40°C to +125°C.

The SRU1038A-221Y is a general purpose inductor, suitable for a variety of applications. It is used in circuits requiring the limitation of current, including DC-DC converters, power relay circuits, pulse circuits, and noise suppression/attenuation circuits. It is also useful in high frequency filter circuits, where an inductor is required for impedance matching, impedance transformation, or signal isolation.

The working principle of an inductor is based on electromagnetic induction. When a DC current passes through a circuit, a magnetic field is generated, which induces a voltage in other circuits connected to it. The magnitude of the induced voltage is proportional to the amount of current passing through the winding.

The SRU1038A-221Y fixed inductor uses the principle of electromagnetic induction to limit current in a circuit. The number of turns of wire used in the winding determines the amount of inductance, and thus the amount of current that can be passed through it. The core material used is also important, as it influences the amount of inductance.

The SRU1038A-221Y fixed inductor is a reliable, general purpose device, suitable for a variety of applications. Its inductance range, temperature rating, and current rating make it ideal for circuits requiring current limitation.
