Fixed Inductors

Fixed inductors are primarily used as a passive element to filter and store electrical energy, provide impedance matching, and produce a desired voltage waveform. The PM125SH-181M is a type of fixed inductor designed to meet specific application requirements and provide an option for a variety of electronic applications.

Application Field of PM125SH-181M

The PM125SH-181M is a high-performance fixed inductor with superior performance characteristics. It is designed for use in high-frequency switching power supplies and flyback converters, output filters of dc/dc converters, and other related applications.

It\'s low-profile and small-size features make it ideal for use in space-constrained and temperature-sensitive applications where high current handling is required. It also operates correctly in harsh environments and can be used in high temperature applications as well. Its wide range of inductance values and current ratings make it an excellent choice for a variety of applications.

Working Principle of PM125SH-181M

The basic principle of a fixed inductor is the conversion of electrical energy into magnetic energy. An inductor is constructed as a coil of wire around a metal core which creates a magnetic field when energized with alternating current (AC). When a voltage is applied across the coil, a current is induced in the coil and the core. The current caused by the voltage creates a magnetic field that opposes the field of the coil. The opposition of the fields creates an inductive reactance that opposes the flow of current, and the magnitude of this reactance is determined by the inductance value of the inductor.

The PM125SH-181M uses the same basic principles as other fixed inductors, however it has been designed to meet high-performance criteria with high temperature and space considerations in mind. The PM125SH-181M uses a flat-wire construction and a metal core that provides high current handling capability and excellent heat dissipation. It also features a low equivalent series resistance (ESR) and a low profile design to reduce electromagnetic interference (EMI).

Conclusion

The PM125SH-181M is a high-performance fixed inductor that is designed for high-frequency switching power supplies, output filters, and other related applications. Its features make it ideal for use in space-constrained and temperature-sensitive applications where high current handling is required. Additionally, due to its low ESR and low profile design, the PM125SH-181M has also proven to be effective reducing EMI. It is an excellent choice for a variety of applications that require a high-performance fixed inductor.
