Fixed inductors are electronic components consisting of a core and a wire wound around it. They are used in a wide range of applications, from powering electric motors to supplying power to consumer products, such as stereos and televisions. The PM20-4R7K is one such fixed inductor, and this article will explore the device’s application field and working principle.

The PM20-4R7K fixed inductor is often used in power applications, such as in filters and voltage converters. It is designed with a ferrite core material, giving it a high inductance value with lower DC resistance. This makes it ideal for use in high current pulses, as well as in high frequency circuits. The inductor also features an epoxy resin coating which gives it excellent insulation against dust and moisture.

In terms of its working principle, the PM20-4R7K inductor functions by allowing electrical current to flow through its winding. The core material acts as a medium for the current, while the wire coils create a magnetic field. This magnetic field helps create a stable current and increases the inductance. As the current is run through the device, the inductance varies based on the frequency and the amount of current. This makes the device ideal for power applications, as the inductance can be tuned to create the desired current.

The fixed inductor is also used in switching power supplies, and is commonly used in automotive electronics. The device is also used in power conditioning of LED lighting applications, as it provides stable current, and is capable of handling high frequencies. Additionally, the PM20-4R7K is used in audio applications, such as amplifiers and PA systems, as the increased inductance helps reduce the distortion and improves the sound quality.

The PM20-4R7K inductor is an efficient and reliable choice for several electronic components. Its core material and wire coil design provide the device with a high inductance value, and the epoxy resin coating ensures excellent performance. This fixed inductor can handle high current pulses as well as high frequency circuits, and is ideal for use in power, automotive, LED lighting, and audio applications.
