Fixed inductors are passive electrical components used to store energy in the form of magnetic fields. The energy is transferred from an electric current flowing through the inductor. They are used in both analog and digital circuits for a wide variety of electrical and electronic applications, from power supplies, amplifiers, and filters. The PM2110-680K-RC is a type of fixed inductor.

The PM2110-680K-RC is a radial-lead fixed inductor with an inductance of 680 nH and a rated current of 2.7 A. It is a shielded unit, meaning it has a metal case with a magnetic core. The construction of the PM2110-680K-RC consists of a wound coil made of copper wire, a ferrite core, and a metal case.

The primary application field of the PM2110-680K-RC is high-frequency circuits, such as switching power supplies, video applications, and cellular phones, due to its high inductance and low series resistance. Additionally, it is commonly used as a filter inductor in line filters to reduce interference in switching-mode power supplies, as well as in DC/DC converters and other circuits where high-frequency noise needs to be suppressed.

The working principle of the PM2110-680K-RC is based on Faraday’s law, which states that the magnitude of the induced electromotive force (EMF) in any closed circuit is proportional to the rate of change of the magnetic flux through the circuit. Specifically, the rotating magnetic field created by the current in the coil induces EMF in the inductor, resulting in a back EMF. This back EMF opposes the current, creating a frequency-dependent impedance. The higher the frequency, the higher the impedance. The inductor also stores energy in the form of a magnetic field.

The PM2110-680K-RC is an excellent choice for applications that require high frequency suppression and inductive performance. Its combination of high inductance and low series resistance is ideal for switching power supplies and other applications where noise needs to be reduced. Despite its small size, the PM2110-680K-RC offers excellent performance in a wide range of applications.
