744902139 Inductors, Coils, Chokes

Inductors are a basic and indispensable component in electrical circuits. 744902139 fixed inductors are widely used in all electronics, especially in drives, controllers, communication, and consumer products. This article will explain its working principle and application field in detail.

Working Principle of 744902139 Fixed Inductors

An inductor is a passive electronic component consisting of a coil of conductive wire wrapped around a core. When an electric current is passed through the coil, it creates a magnetic field around the core, pushing the magnetic flux generated by the current into the core. When the current stops flowing, the magnetic flux is released and an electromagnetic field is created. This is the basic working principle of an inductor.

The 744902139 fixed inductor is an LRU-type device formed by extruding a rolled steel sheet into a wave-shaped form. A wave of 80mm to 120mm long is produced, and then the core is wrapped around the wave. The core material consists of iron and steel alloys. Windings of enameled copper wire are applied to the core, with winding numbers typically ranging from 30 to 50 turns.

Application Field of 744902139 Fixed Inductors

744902139 fixed inductors are widely used in electronic circuits, especially in the drives, controllers, communications, and consumer products. It can be found in applications such as DC/DC converters, AC/DC switching power supplies, DC-to-DC converter magnetics, controllers, amplifiers, switches, and CRT television power supplies.

In addition, 744902139 fixed inductors are also used in the automotive electronics industry in applications such as electric power steering (EPS) and oxygen sensors. As the EPS requires a wide electric output, the use of 744902139 fixed inductors in this application improves energy efficiency and helps extend the life of the system.
