Fixed Inductors

Fixed inductors are electronic components made of either ferrite or ceramic, wound with very thin wire. The PCMB042T-R47MS is a common example of such a fixed inductor. Its use and working principle are explained in detail below.

PCMB042T-R47MS application field

The PCMB042T-R47MS is a surface mount fixed inductor with a 0.003µH inductance. This type of fixed inductor is used primarily in power supplies, filter circuits, and DC-DC converters. As a surface mount inductor, it is well-suited to tightly spaced, low-profile applications due to its small size and light weight.

Working principle

A fixed inductor works by slowing the change of current flowing through it. This is accomplished by creating a temporary magnetic field in opposition to the current flow. The inductance is determined by the amount of wire used, the shape and size of the coil, and the material the coil is wound onto. The larger the inductance, the greater the opposition to changes in current flow.

The PCMB042T-R47MS is a 0.003µH inductor. This small value of inductance makes it especially useful in small-scale power supplies and filter circuits. The small size and light weight of the PCMB042T-R47MS also make it a particularly good choice for tight-fitting applications.

Conclusion

The PCMB042T-R47MS is a fixed inductor composed of a ferrite core and wire coil with a 0.003µH inductance value. Its small size and light weight make it well-suited to tight-spaced, low-profile applications. It is primarily used in power supplies, filter circuits and DC-DC converters, where its small inductance value makes it an ideal choice.
