Fixed Inductors

PM75-220K Application Field and Working Principle

Fixed inductors, like the PM75-220K series, are electromechanical components designed to store and deliver electrical current. A fixed inductor consists of several components, including an inductor, an enclosure, and an air gap for insulation. The function of an inductor is to restrict the level of current flow in one direction, while allowing a higher level of current to flow in the opposite direction.The PM75-220K series of fixed inductors is designed for a variety of uses. They are suitable for various applications in power supplies, such as rectifier circuits, EMI filters, power factor correction components, high frequency rectifiers, and RF power amplifiers. In addition, these inductors can also be used for audio applications, such as electric guitar pickups, active crossovers, speaker protection circuits, and crossover networks.The working principle of the PM75-220K series of fixed inductors is relatively simple. When the current enters the inductor, it is attracted to the primary winding. This current then flows through the copper core to the secondary winding. As the current passes through the copper core, it creates a magnetic field. The magnetic field causes a voltage to be induced in the secondary winding, which is equal to the voltage in the primary winding. This induces an opposite, or reactive current flow.The PM75-220K series of fixed inductors are designed to have low resistance and high stability. This helps to ensure that the inductor can withstand the various types of electrical loads and fluctuations that it may come in contact with. In addition, the inductors are designed to be thermally stable, meaning that they will not heat up too quickly or too much when under load. Finally, they are designed to be relatively compact, meaning that they can fit in even the smallest of spaces.Overall, the PM75-220K series of fixed inductors are a versatile and dependable component. With their wide range of uses and their high stability and resistance, they are an excellent choice for a variety of applications. From power supplies to audio applications, the PM75-220K series of fixed inductors can help to ensure that your project is up and running and running efficiently.
