Fixed inductors perform an important role in the electrical applications field. They are used to store electrical energy in a magnetic field and then release the energy back into the system. The role of an inductor in an electrical circuit is to provide a constant current in spite of voltage and frequency variations. Fixed inductors can be used in a wide range of power applications, from power conversion to DC power supplies.

The PM20S-2R7K is a fixed inductor that has a wide application field. It is often used in DC-DC converters, signal processing applications, and charging circuits. The inductor has a nominal inductance of 2.7 mH (millihenry) and a maximum DC current rating of 0.6640 A (amps). The maximum operating temperature of the component is +105°C.

The working principle of the PM20S-2R7K can be described using Faraday\'s law of induction. This states that the electromotive force generated in a circuit is proportional to the rate of change of the magnetic flux through the circuit. The inductor is placed in a circuit where an alternating current (AC) is flowing. As the current passes through the winding of the inductor, it creates a changing magnetic flux in the circuit. The changing magnetic flux induces an electromotive force (EMF) in the circuit, which is known as back EMF. The voltage induced in the inductor will be equal to the back EMF.

The magnitude of the voltage induced in the inductor is determined by the inductance of the inductor, the rate of change of the current, and the frequency of the input AC. The voltage is the sum of the inductive reactance (XL) and the resistance of the component. XL is represented by the equation: XL = 2πf•L, where f is the frequency of the input current and L is the inductance of the inductor. This equation shows that at higher frequencies, the inductive reactance across the inductor will increase.

The PM20S-2R7K inductor has a good power density, high efficiency, low THD (total harmonic distortion), and excellent temperature stability. Its high power density makes it an ideal choice for applications where space is limited. It also has an excellent price/performance ratio, making it an excellent choice for cost-sensitive applications.

The PM20S-2R7K is an excellent choice for a variety of applications due to its wide application field and excellent working principle. It can be used in DC-DC converters, signal processing applications, and charging circuits. Its high power density, high efficiency, and excellent temperature stability make it an excellent choice for applications that require high performance at an affordable price.
