What is Fixed Inductors? A fixed inductor is a device which stores energy as a magnetic field. It is typically made up of a coil of wire which stores and transfers energy to the surrounding circuit. Fixed inductors can be found in many electronic products like radios, computers, and even household appliances.

The PM2120-391K fixed inductor is a common device found in various electronic products. It is used to reduce the current flow in an electrical circuit by inducing a magnetic field into the conductor. This magnetic field resists the current flow and helps maintain a certain level of the current.

The PM2120-391K is an epoxy-coated, nickel-zinc core fixed inductor. It is widely used in power filtration, coupling as well as decoupling circuits. The inductor has a maximum DC resistance of 4 ohms and an impedance up to1000 ohms. Additionally, the inductor has a low temperature coefficient, which helps provide stable operation across a wide temperature range. Also, the inductor is capable of supporting alternating current (AC) frequencies from DC to 1 MHz.

The PM2120-391K inductor has a variety of applications. It is commonly used in power supplies and electric systems like AC/DC converters, inverters, and motor drives. It is also used in audio amplifiers, switch mode power supplies, and noise filters.

The PM2120-391K inductor works through the principles of Faraday\'s law of magnetic induction. It uses alternating current (AC) to induce a magnetic field into its core, which then resists the current flow. This prevents the voltage from increasing or decreasing too quickly and helps to maintain a constant current. The inductor also helps reduce unwanted noise and interference from the electrical circuit.

The PM2120-391K inductor is a versatile component and is used in a variety of applications, ranging from switch mode power supplies to audio amplifiers. This inductor is suitable for use in a variety of temperature conditions and can be used with both AC and DC circuits. With its low temperature coefficient and high current capability, the PM2120-391K fixed inductor is an ideal choice for many electronic projects.
