Fixed inductors are essential components of electronic circuits that store electrical energy in the form of a magnetic field. The PM20S-820K is a common type of fixed inductor. It is used in many different applications, and its working principle can be understood with some basic knowledge of electronics and inductance.

Applications

PM20S-820K inductors are used in a variety of applications, including audio filtering, radio frequency interference (RFI) suppression, high frequency signal switching, low pass filters, and noise suppression. They are also often found in electronic circuits that require a constant current or voltage.

PM20S-820K inductors can also be used in computers and other electronic devices. They are often found in motherboards, hard drives, and graphics cards, where they provide the necessary filtering to ensure that the signals being sent between components are free from interference or noise.

Working Principle

An inductor is a device that stores energy in the form of a magnetic field. The PM20S-820K inductor is a special type of inductor that uses a ferrite core to store energy more efficiently and reduce the size of the component. The inductor consists of an iron core wrapped with a conducting wire. When a current flows through the wire, a magnetic field is created in the core. This field stores energy and can be used to provide a voltage when the current is removed.

The capacitor inside the PM20S-820K inductor also plays an important role. This capacitor helps to smooth out the frequency of the electric current that passes through the device, allowing the inductor to perform its filtering functions more effectively. The capacitance of the capacitor is dependent on the size of the core and the amount of wire wrapped around it.

The inductance of the PM20S-820K depends on the number of turns of wire used and the size of the core. Generally, the higher the number of turns of wire, the higher the inductance. Also, the larger the core, the higher the inductance. The inductance can also be controlled by using a different type of core or by adding a ferrite material to the core. This can be used to adjust the inductance to match the requirements of the application.

The PM20S-820K can operate at frequencies from 10kHz up to 100MHz, depending on the number of turns and size of the core. It has a maximum current rating of 0.5A, and a saturated inductance of 68µH.

In summary, the PM20S-820K is a type of fixed inductor used in many different applications. It uses a ferrite core to store energy in a magnetic field, and a capacitor to help smooth out the signals that pass through the device. The inductance of the device can be adjusted by altering the size of the core or adding a ferrite material to the core. The device is able to operate at frequencies of up to 100MHz and has a maximum current rating of 0.5A.
