Fixed inductors are essential elements for many electrical and electronics designs, acting not only for current limitation or energy storage but also for frequency selection, impedance matching and more. The PM20-6R8K fixed inductor is one of the many components used for these purposes, and its application as well as its working principle will be described in greater detail below.

The PM20-6R8K is a low-profile device designed to provide improved high-frequency characteristics with minimal impact on the layout of any circuit. Its use is recommended in applications where impedance matching or energy storage is required, such as mobile computing as well as in audio-visual and communication equipment. It can also be employed to bypass high-frequency signals, protect sensitive circuits, reduce interference, or to filter ripple current. This component can operate at up to 200 degrees C allowing it to handle higher levels of heat in demanding applications where other inductors might easily overheat.

The PM20-6R8K is a closed magnetic core inductor made of high-permeability material and features two leads for easy connection. When in operation, an alternating current is induced in the inductor, producing a magnetic field. This field induces a voltage across the two leads proportional to the rate of change of the inductor’s magnetic field. The magnitude of the induced voltage, as well as the amount of inductance, is primarily determined by the number of turns of wire that make up the inductor.

In order to reduce the effects of parasitic circuit elements such as resistance and capacitance, the PM20-6R8K utilizes a closed magnetic core consisting of high-permeability materials which efficiently concentrate the magnetic field, thus raising the inductance with minimal core losses. This leads to improved high-frequency performance and power handling capability. The use of a closed magnetic core also protects the inductor from external magnetic fields, as well as reducing the core’s hysteresis losses.

The PM20-6R8K is an excellent choice for a diverse range of circuit designs, allowing engineers to take advantage of its high-frequency performance and power handling capability without disrupting the layout of the circuit. Its magnetic core construction and materials help to provide improved characteristics which are useful for reducing interference, filtering out noise, or matching impedances.
