Fixed Inductors

A fixed inductor is an electronic device which is used to store energy in the form of a magnetic field. The most common application for a fixed inductor is in the manufacture of circuits. In a circuit, an inductor acts as an energy storage device, allowing current to flow in a direction that is opposite to the direction of the main current flow in the circuit. This helps to regulate and control the current, voltage and power in the circuit.

The PD73R-224K fixed inductor can be used to store energy in either AC or DC circuits. Its characteristic physical appearance is an axial molded inductor with an insulation sleeve and two internal silicone cores. It has a rated current carrying capacity of 4.2A, a rated DC resistance of 8.0mΩ and a rated inductance of 28.7mH.

The PD73R-224K fixed inductor has a wide range of applications. It can be used as a filter inductor to suppress unwanted high frequency noise in automotive or digital circuits, or as an LC filter, where it can be used to filter out AC ripple from DC power supplies. It can also be used for controlling power output in intelligent power switches and voltage regulators. It is also suitable for applications which require high inertial characteristics, like controlling the frequency and phase of the output signal from pulse transformers.

The working principle of the PD73R-224K is based on Faraday’s Law, which states that when a conductor is placed in a changing magnetic field, an electromotive force is induced in it. This means that when current passes through a fixed inductor, the inductor will create a magnetic field in proportion to the current. The field creates a ‘back EMF’, or an opposing voltage, that opposes the current, thus creating a resistance to its flow. This resistance reduces the current in the circuit, allowing it to be more easily controlled.

The PD73R-224K fixed inductor is a reliable and versatile device, allowing for the creation of circuits with high efficiency and stability. Its high current capacity and low DC resistance make it suitable for a wide range of applications. It is a cost-effective option for manufacturers who require a reliable inductor.
