Fixed Inductors

Inductors are one of the oldest electrical components in the world. They can be used in many applications and are made from a variety of materials, including wire, semiconductor material, or ferrite. Fixed inductors are those whose inductance value remains the same despite the application. In particular, the 2890R-22K is a chip surface mount fixed inductor with a rated inductance of 22 microhenries.

Application field

The 2890R-22K is a general purpose, self-shielded surface mount fixed inductor with a temperature rating of -40C to +125C. It is particularly suitable for consumer-level electronic products because of its low cost and small size. Moreover, it is widely used in communications, automotive electronics, and military equipment.

The 2890R-22K is also a reliable power inductor, due to its high saturation current. It can handle high frequency applications due to its low core loss. In addition, it features high current density, an ease on-board mounting, and good heat dissipation capabilities.

Working Principle

The 2890R-22K fixed inductor is composed of a coil of insulated copper wire, wrapped around a core made from iron. This arrangement of components produces an electromagnetic field that resists changes to the current flow, thus allowing for the inductor to store energy. This energy is typically released as a back electric current when the current is switched off or reversed.

The current is then reduced as the magnetic field created by the coil decreases. This decrease in current is measured as a voltage drop across the inductor, and is known as inductance. It is this property of inductance that makes it particularly attractive for use in high frequency applications, such as audio and power conditioning.

The 2890R-22K fixed inductor is typically used in applications needing to drive high power loads under varying conditions. Its high-torque core minimizes magnetic energy leakage and produces a stable current, which is also well suited for ripple filter applications.

The 2890R-22K is designed to provide plenty of headroom and can handle power up to 3A at temperatures up to 125C. It also features high self-resonance frequency and low core loss, making it a reliable and efficient power inductor suitable for most applications.
