PM5022-2R2M-RC

Fixed inductors are electronic components that store electrical energy. The energy is stored in the form of a magnetic field generated when current flows through the wire wound around a soft ferromagnetic core, usually made of powdered iron. The PM5022-2R2M-RC inductor is one of many varieties of fixed inductor which has specific application fields and a distinct working principle.

Application Fields

The PM5022-2R2M-RC is a power inductor ideal for use in automotive, IT, and consumer electronics applications. It is a surface mount device, available in a maximum package size of 15.2 mm×11 mm×6 mm, and can handle rated current of 2.9 A with a rated voltage of 50 V. It has a nominal inductance of 2.2 µH and a saturation current of 5.7 A.

Because of its package size and maximum rated current, it can be used in a wide variety of mobile applications, such as laptop chargers and power banks. It is also suitable for applications with a higher switching frequency of up to 5 MHz, making it a great choice for mobile phone, game, and other digital applications.

Working Principle

The PM5022-2R2M-RC is designed around the working principle of Faraday’s Law of Induction. Basically, when current passes through the inductor a magnetic field is generated. This magnetic field creates a voltage in the inductor that opposes the flow of current. As the current continues to flow, this voltage increases until it reaches a point where it balances the force of the current. At this point, the current remains constant.

The PM5022-2R2M-RC is designed to maintain this balance of voltage and current even in high switching frequency applications. It can also maintain high linearity and low thermal impedance. The combination of these features makes the PM5022-2R2M-RC the ideal choice for automotive, IT, and consumer electronics applications.
