2890-39H

Fixed inductors are common components in electrical circuits, and are essential in providing proper inductance values for the operation of devices such as amplifiers, radios, transformers, and filters. The 2890-39H is one of the most popular fixed inductors used in a variety of applications. This article will be discussing the 2890-39H application field, its working principle, and advantages of using this inductor.

Application Field

The 2890-39H is primarily used in the field of electronics for a variety of purposes. It is especially useful for applications which require high inductance values, such as in antenna matching circuits, radio and television tuners, high voltage power supplies, and high frequency oscillators. In addition, it is also popular for use in harmonic filters, power factor correction capacitors, switched-mode power supplies, and high speed switching circuits.

Working Principle

The 2890-39H fixed inductor works by using a wire winding to create an electromagnetic field. When current flows through the winding, the magnetic field generated by the coil generates an opposing electric field, thereby increasing the inductance. The total inductance of the 2890-39H is dependent on the number of windings, the core material, and the air gap between the windings.
