4379-473JS

Fixed inductors, also called fixed coils, are electrical components composed of three basic elements: a conductor, an insulating material, and some type of magnetic device. They are used to store electrical energy and convert alternating current to direct current, or vice versa. The 4379-473JS application field and working principle are routinely used in automotive electrical systems such as starting and charging circuits.

Construction

A fixed inductor is constructed of several individual components. First, a coil of wire is wrapped around an iron core. The amount of turns or wraps of wire is important in the performance of the inductor, as it will determine the inductance value. The wire can be aluminum or copper and is usually wound in a helical fashion. The iron core is stationary and can be an open form or a closed form with an air gap. An air gap is important for increasing the inductance of the coil. The coil is wrapped with an insulating material to protect it from environmental factors as well as shorting out when it comes in contact with other components.

How Does It Work?

When a voltage is applied to the coil, a magnetic field develops around it. When the current changes, the magnetic field fluctuates. The fluctuations of the magnetic field induce an electromotive force, resulting in a reverse voltage to be generated in the coil. This reverse voltage opposes the applied voltage, creating an inductive store of energy, which acts like a resistor. This resistive force is what makes fixed inductors useful for regulating and stabilizing current and voltage in a circuit.
