Fixed inductors are devices made of coils of wire wrapped around either ferrite or iron. They are used to provide electrical current, control power-handling capabilities, and stabilize voltage or frequency, among other applications.

One of the most common fixed inductors available is the SPM4015T-R47M. The device is a general-purpose radial-style inductor that can handle very high current and is designated as a RoHS compliant product. The inductor has a small size of only 4.5x5mm, making it suitable for a variety of applications in communication and consumer electronics, office automation, and medical equipment.

The SPM4015T-R47M is manufactured with a feature called a core inductance which is a measure of the amount of inductance created between the layers when an electrical current is passed through it. This core inductance enables devices to more efficiently store and discharge energy.

In terms of its applications, the SPM4015T-R47M is used mainly in filters and voltage regulator circuits. The device is usually placed between two signal lines to protect the circuit from noise and voltage spikes. The inductor increases the circuit’s frequency response and allows it to react better to different frequencies. Additionally, the device helps reduce high-frequency interference by absorbing it and preventing it from entering the circuit. It also helps stabilize voltage or current fluctuations.

The working principal of the SPM4015T-R47M is based on the fact that when a charged electric current passes through the inductor’s coil, it builds up a magnetic field around it. This magnetic field then attracts and repels other magnetic fields and, in turn, induces a current in the coil, which is referred to as inductance. This inductance is equal to the amount of magnetic field generated by the coil, multiplied by the number of turns in the coil.

Overall, the SPM4015T-R47M is a useful fixed inductor for filtering and stabilizing voltage or current, and it is used mainly in communication and consumer electronics as well as medical and office automation applications. Its core inductance enables the device to efficiently store and discharge energy, and the working principal of the inductor is based on the creation of a magnetic field surrounding the coil when a current is applied.
