Fixed inductors, such as the PM2120-1R8M-RC, are an important part of any electronic system, as they help store energy while protecting the other components from damage. The PM2120-1R8M-RC is a high temperature surface mount inductor with a ferrite core and copper lead frame. It is designed to have low leakage current, low parasitics, high temperature coefficient, and low inductance. It is well-suited for a variety of applications ranging from low-power LoRa applications to high-power RF designs.

The PM2120-1R8M-RC application field mainly focuses on low to medium-powered electronics, such as telecommunications, or industrial electronics. This device is suitable for a variety of applications that require low self-heating, low insertion loss, and good reliability. Some of the common applications where this inductor finds use are base station power supplies, satellite systems, communication systems, commercial amplifiers, and switching power supplies.

The working principle of the PM2120-1R8M-RC is based on the theory of magnetic induction, where electric currents are generated by moving or changing magnetic fields. This device consists of a ferrite core that stores energy, a copper coil wound around the core, and two lead frames- one connected to the positive terminal of the inductor and the other to the negative terminal. When an AC or DC signal is applied to the lead frames, the current flow generates a magnetic field in the ferrite core, which stores energy. When the current flow decreases, the stored energy is released back into the circuit, creating an inductor effect.

The PM2120-1R8M-RC is designed to handle large current and voltage spikes without damaging the component. This is accomplished by its high temperature coefficient, which prevents the stored energy from reaching dangerous levels. The low leakage current also prevents the component from dissipating energy as heat, lowering the device’s temperature. The low parasitics and tight inductance tolerance of the PM2120-1R8M-RC ensures that signals are accurately transmitted and received with minimal electrical noise.

In a nutshell, the PM2120-1R8M-RC is an ideal fixed inductor for various low to medium-powered electronic applications. Its low leakage current, high temperature coefficient, and tight inductance tolerance makes this device suitable for a variety of applications such as base station power supplies, satellite systems, commercial amplifiers, and switching power supplies. It is capable of handling large current and voltage spikes without damaging itself or the other components, and its low parasitics help reduce electrical noise in the circuit.
