Fixed Inductors: PM105-331K

PM105-331K is a fixed inductor device that is primarily used in the high-frequency switching power supply industry and the converters, resonators, chokes, transformers and other components and systems that make up the electrical networks associated with them. A fixed inductor is defined as "an electronic component that stores electrical energy as the magnetic field produced when current flows through it."

Application Field

PM105-331K is primarily used as either a series or parallel-connected inductor in switching power supplies. This type of power supply produces a high frequency alternating current from the direct current produced from a rectifier device. The inductor works with other components, such as switches and transformers, to create a stable voltage and current output. Inductor devices can also be used in other applications for filtering, matching impedance, tuning, and energy storage.

Working Principle

PM105-331K, like all inductors, works by storing energy in a magnetic field when a current flows through it. The inductor is composed of an electric conductor, typically a coil of wire that is wound around a core of magnetic material, such as iron or ferrite. When a direct current is applied, an electromotive force (EMF) is induced in the windings, creating a magnetic field around them. This magnetic field generates a counter EMF that opposes the flow of current. The sum of this opposition of the current is known as inductance. This inductance can be controlled by changing the number of windings, the core material, and the geometry of the coil.

When an alternating current (AC) is applied to the PM105-331K, the magnetic field surrounding the windings is constantly changing. This induces a voltage on the windings that is proportional to the rate of change of the magnetic field in the core. The rate of this change in field generates a current that is also proportional to the rate of the field change. As a result, the total charge stored on the inductor is proportional to the current that is passing through it.

Conclusion

Overall, the PM105-331K is a fixed inductor device that is primarily used in the high-frequency switching power supply industry and associated components. It works by producing a magnetic field that opposes and stores energy when a current is applied. This type of device is used for filtering, matching impedance, tuning, and energy storage applications.
