Fixed Inductors

A fixed inductor is an electronic component that stores energy in the form of a magnetic field. It is used in a wide variety of applications and is found in nearly every electronic circuit. The PM42S-390 is a type of fixed inductor used in both analog and digital circuits.

Application Field

The PM42S-390 is used widely in power supplies, amplifiers, oscillators, and instrumentation systems. It is suitable for use in high-frequency applications and can operate over a wide range of temperatures with minimal fluctuation in performance. It is also useful in motor control and pulse generator circuits.

The PM42S-390 can be used for AC power line filtering applications as well. It is an ideal choice for these applications as it can effectively reduce harmonic content and reduce power loss. In addition, it is capable of handling high voltages and current levels.

Working Principle

The PM42S-390 is an inductor which functions by storing energy in the form of a magnetic field and using that energy to oppose changes in current. The magnetic field is created when current passes through the winding of the inductor, and the inductor\'s ability to keep current stable is determined by its inductance.

When an AC voltage is applied to the inductor, the current through the inductor is sinusoidal in shape and follows the same waveform as the applied voltage. As the voltage increases, the current is initially low and then increases gradually as the voltage increases. As the current increases, the magnetic field surrounding the inductor increases as well. When the voltage begins to decrease, the current follows suit and slowly dissipates the energy stored in the inductor.

This is the basic principle of operation of an inductor. The PM42S-390 is an effective type of inductor and is widely used for applications that require the transfer of AC power or the attenuation of unwanted noise in electronic circuits.
