Fixed Inductors- 2890R-26F Application Field and Working Principle

Inductors can be classified into two distinct categories: variable inductors and fixed inductors. Fixed Inductors are passive two-terminal electrical components used to build up or block electrical circuits. The term “fixed” comes from the fact that these inductors have a constant inductance value throughout their entire working range. Although they are simple in concept, they can be used to implement complex circuit features such as filters, buffers, and voltage converter circuits.

One of the popular fixed inductors is the 2890R-26F, which is designed specifically for use in automotive applications. This inductor has a rated inductance of 2.19 μH, a rated current of 2.5A, and a saturation current of 3.3A. It features a metallic shielding case, insulated mounting pins, and a ferrite core which has been hermetically sealed.

The 2890R-26F inductor is typically used in automotive Power Supply circuits. Power Supply circuits consist of converting DC power from a vehicle\'s battery into AC power for providing an appropriate voltage to other devices. The inductor is connected in a bridge rectifier circuit in order to convert the AC power from the alternator output into a DC signal. The inductor helps to filter the DC signal, removing any unwanted frequencies, and allowing smoother operation of the circuits.

The working principle of the 2890R-26F inductor is based on the formation of a magnetic field when a current is applied through the windings. This electric current generates a magnetic field in the core of the inductor that opposes the applied current. This phenomenon is known as inductance, and it is what allows the inductor to store and release energy. The amount of inductance is determined by the number of turns in the winding, the core material, and the cross-sectional area of the inductor.

The inductor also acts as an energy filter. When ac current is applied to the inductor, it blocks any low-frequency signals, allowing only the high-frequency signals to pass, while still allowing the low-frequency signals to be filtered from the output. This allows the device to produce higher quality output signals, as well as reduce interference from other circuits.

The 2890R-26F inductor is a versatile and reliable component that is widely used in a variety of automotive applications. It can be used to build up or block electrical circuits, filter noise, and improve system quality. It is a reliable and dependable component that can be used in a wide range of automotive power systems.
