Inductors play an important role in many electrical circuits by providing electrical energy storage in the form of magnetic fields. There are a variety of inductors available on the market, including fixed inductors. The RCR664DNP-821K is a type of fixed inductor that is useful for high power switching applications. This article will discuss the application field and working principle of the RCR664DNP-821K.

The RCR664DNP-821K fixed inductor is designed for high-power applications, primarily in buck converters. As a buck converter is a DC to DC converter that steps down voltage, having an inductor with high inductance to support this type of application is important. The RCR664DNP-821K has large inductance value of 8.2 mH, to provide maximum current for the application. It also has an air-gap structure, which reduces core loss and increases saturation current. The inductor also has a maximum DC current of 100A, and a maximum DC voltage of 250V.

In addition to the high power specifications, the RCR664DNP-821K also has a low profile design. This helps to save the physical space on the PCB, as well as reduce the overall weight when compared to other inductors. The inductor also has a rated temperature of up to 125° C, making it suitable for operation in extreme environments.

In terms of working principle, the RCR664DNP-821K fixed inductor works by storing electrical energy in the form of a magnetic field. This is done by passing a steady electric current through a conductor wrapped in a coil. This generates a magnetic field around the coil, which is used to store the electrical energy. This process is referred to as self-induction, and is used in many electrical circuits.

In the case of the RCR664DNP-821K fixed inductor, the current will flow one way across the primary winding, and will then be reflected in the secondary winding. As the primary current increases, the magnetic field increases and the inductor stores more energy. When the current decreases, the magnetic field decreases and the inductor releases the stored energy. This is how the inductor helps to regulate current in a circuit.

The RCR664DNP-821K fixed inductor is an ideal choice for high power switching applications. Its high inductance value, low profile design, high current and voltage rating, and extreme temperature rating make it a reliable choice for a variety of applications. Additionally, its self-induction working principle make it easy to understand and utilize in electrical systems.
