Fixed Inductors

Fixed inductors are essential components in power systems that play an important role in storing energy and providing protection against certain types of faults. The PM2120-100K is an inductor specifically designed for use in professional energy systems and applications. This article will cover the application fields and working principle of the PM2120-100K.

Application Fields

The PM2120-100K is a 9-turn 3-layer inductor suitable for use in telecommunications, information technology, automation control, consumer electronics, and auto-electronic security applications. This inductor is especially suitable for high power output transformers and power supplies that require a large capacity. It is also suitable to be used as a multi-coil transformer in mobile phone chargers, laptop computers, and other electronic equipment.

The PM2120-100K provides excellent circuit stability, and its superior power-handling performance also makes it an excellent choice for power supplies with low-frequency switching. Its high power-handling capacity and small size make it an ideal printer control board component.

The PM2120-100K is also suitable for use in charging broadband devices, such as routers and network appliances. Its high power-handling capacity makes it an ideal broadband device charger. Furthermore, it is also suitable for use as a core component in high-grade sound reinforcement systems, delivering superior acoustic performance.

Working Principle

The PM2120-100K is based on the principle of inductance. In the simplest terms, an inductor stores energy in a magnetic field when an electric current passes through it. In an AC circuit, the current will alternate between positive and negative peaks and be stored in an inductor as a magnetic field. As the current changes, so does the magnetic field and, as a result, an EMF (electromotive force) will be generated.

The PM2120-100K uses several layers of copper foil wound together in a 9-turn order. The copper foil acts as a conductor and stores the energy, creating a magnetic field between the foil and the inductor. The current passing through the inductor will cause a voltage drop as the energy is transferred from the inductor into the magnetic field, creating a voltage across the inductor.

The PM2120-100K also has protective features built-in to ensure high safety in case of a power failure or over-current. A self-resetting thermal fuse is integrated into the device, protecting it from short circuits and other electrical hazards. This self-resetting feature allows the device to recover from an overload of electrical current without needing manual resetting.

The PM2120-100K is a highly-reliable and efficient inductor component. Its exceptional performance makes it an ideal choice for a variety of energy systems and applications. Its compact size makes it suitable for use in various telecommunications equipment, information technology systems, vibration sensing systems, and other electronic and automotive applications. Many users have also found the PM2120-100K to be ideal for use in high-grade sound reinforcement systems. Its superior acoustic performance and power-handling capacity make it an excellent choice for this application.
