Fixed inductors are passive components of electronic equipment that are typically wound to specific inductance values. The 2890R-20H is one type of common fixed inductor. It has a wide range of applications in many kinds of electronic circuits and systems.

The 2890R-20H is a cylindrical component, measuring 25.4mm in diameter and 50 mm in length. It has an inductance value of 20H and an impedance of 50kHz. The operating temperature of this device ranges between -40°C and +85°C, and it features a storage capacitor of 80pF. The device also features a unipolar coil winding and a ferrite core, which provides magnetic shielding, minimizes noise, and optimizes power consumption.

The 2890R-20H inductor can be used in a wide variety of applications, from digital and analog circuits to major power delivery systems. Its typical application field includes telecommunication networks, computer networks, medical electronics, instrumentation, and control systems. When used in power delivery systems, the 2890R-20H inductor is used to construct high current filters, transformers, and power supplies.

The working principle of the 2890R-20H is based on Faraday\'s law of induction. This law states that when a conductor is placed inside a changing magnetic field, an electromotive force is induced in it. The 2890R-20H uses this principle by connecting its ferrite core to the main power supply. When an alternating current flows through the coil, it creates a magnetic field, which induces an electromotive force in the coil. This electromotive force is fed back to the power supply, creating a loop. This loop helps to maintain the stability of the voltage and minimize losses caused by inductive effect.

The 2890R-20H is an effective and reliable inductor used for moderate power supply systems and low level signal processing. Its wide field of applications and secure working principle make it an ideal choice for most electronic circuitry. It is an important component that ensures the proper operation and long-term operation of electronic equipment.
