Fixed inductors, also known as power inductors or inductor coils, are passive electronic components that are designed to store electrical energy in their magnetic field. They are typically found in power supplies, such as those used in computers and cell phones, and act as a buffer between the DC input and the AC output. They are used to reduce electrical noise, control current, provide stability, and extend the life of the power supply. Fixed inductors are available in a wide variety of shapes and sizes, and are designed to meet specific requirements.

The PM2120-8R2M is a fixed inductor manufactured by Power Magnetics Inc. It is designed to provide superior performance in the field of DC to AC conversion. The PM2120-8R2M is ideal for applications that require a low profile, high-efficiency power supply using non-law current control. It features a shielded iron core construction and a resistor coil assembly with an operating temperature range of -40°C to +85°C.

The PM2120-8R2M has a rated saturation flux density of 119 kA/m and a maximum energy storage capacity of 1.68mJ. It is rated for up to 8A of continuous current with a peak current of 20A and has a low DCR of 0.21Ohms, providing a high power transfer efficiency of up to 99%. It also has a high ripple current rating of up to 4.2A, making it suitable for switching power supplies and other high-power applications.

The working principle of fixed inductors is relatively simple. When a current is passed through the inductor, it creates a magnetic field that stores electrical energy for later use. This process is called inductance, and when the current is removed, the stored energy is released back into the circuit. This process is used in power supplies to convert DC power into AC power, and also for power conditioning and voltage regulation.

The PM2120-8R2M has a wide range of applications, including power supply filtering, noise reduction, current control, and power conversion. It can be used in both commercial and industrial applications, such as switching power supplies, automotive power systems, and energy storage systems. It is also suitable for a variety of circuit configurations, including series and parallel circuits, and is compatible with high-frequency switching applications.

In conclusion, the PM2120-8R2M is a high-performance fixed inductor designed for superior performance in DC to AC conversion. It is well suited for a variety of applications, including power supply filtering, noise reduction, current control, and power conversion. It is available in a wide range of sizes and configurations and is compatible with a variety of circuit configurations and high-frequency switching applications.
