Fixed inductors are essential components found in electrical and electronic circuits, and performing a wide range of functions. They are available in many different shapes, sizes and configurations, and the PM105-470K-RC is one such example. This article will aim to outline the application field and working principle of the PM105-470K-RC, in order to provide a comprehensive understanding of what it is and how it works.

Application Field

Fixed inductors have a wide range of applications, ranging from providing energy storage (to power devices during high power consumption events) to providing filter components for alternative current power supplies. The PM105-470K-RC is well-suited to these applications, as a compact and cost-effective solution. As such, it finds widespread use in power electronics, radio frequency applications and other alternative current power supplies.

As a result, the PM105-470K-RC finds use in many diverse products, such as motor drivers and portable electronic equipment. In addition, it is often used in power supplies found in commercial and industrial environments, due to its ability to provide reliable performance even in the presence of fluctuating conditions.

Working Principle

Like all inductors, the PM105-470K-RC is based on the basic principle of electromagnetism. The inductor consists of two basic components: a core (usually made of ferrite) and a coil (made of copper wire). The core acts as the magnet, and the coil acts as the electric field. When a changing current passes through the coil, the coil pickups the changing voltage of the power source and inducts a corresponding magnetic field around the core, which then produces an opposing current of the same magnitude (counter inductance) which is known as the counter electromotive force (CEMF). Thus, the inductor provides a small amount of resistance to the flow of current.

In order to ensure the PM105-470K-RC is capable of providing reliable performance, additional components are incorporated into its design and construction. These components, usually found on the PC board, include protection circuits, rectifiers, and thermistors, all of which help to ensure the inductor is able to provide steady performance in the presence of fluctuating conditions.

In conclusion, the PM105-470K-RC is a fixed inductor that finds widespread use in power electronics and many other applications. It is a compact and cost-effective solution that is capable of providing reliable performance in potentially hazardous conditions. Thanks to its intricate design and construction, the PM105-470K-RC is a highly versatile and reliable inductor that can be used in a wide range of applications.
