Fixed inductors are found in a variety of applications including filters, impedance matching, DC-DC converters, switching power supplies, and voltage regulators. The PM20S-R22M is a type of fixed inductor that is ideal for use in DC-DC power converters due to its high efficiency, high frequency response, and high power rating. This article will look at the application field and working principle of the PM20S-R22M.

The PM20S-R22M is a type of axial inductor with a single, coreless-ring construction. This type of inductor has a very low resistance and is suitable for high frequency operations. It is designed to operate in an ambient temperature range of -40 to +85°C, allowing it to be used in a wide variety of applications. The inductor has a magnetic permeability of approximately 500mH/m and a maximum operating temperature of 155°C. The inductor also has a very low profile, making it ideal for use in space-restricted areas.

The PM20S-R22M is most commonly used in DC-DC power converters due to its low resistance and high frequency response. It is also ideal for applications such as filters, impedance matching, switching power supplies, and voltage regulators. These applications all require an inductor with a high power rating, low resistance, and high frequency response, which the PM20S-R22M is able to provide.

The working principle of the PM20S-R22M is based on the concept of inductance. When an alternating current (AC) is applied to an inductor, the current passes through the coil, inducing a magnetic field. The magnitude of the current and the strength of the magnetic field will depend on the inductance of the coil. As the current increases, the magnetic field increases, causing inductive reactance. This reactance is what causes the inductor to have a low resistance and a high frequency response.

The PM20S-R22M is a versatile and reliable inductor, making it an ideal choice for use in a variety of applications. Its low resistance, high power rating, and high frequency response make it well suited for use in DC-DC power converters, filters, impedance matching, switching power supplies, and voltage regulators.
