2890R-44H

Fixed Inductors

Inductors, also known as reactors and coils, are passive components used in electrical and electronic circuits for energy storage and signal transformation. An inductor usually consists of a conducting wire in the form of a coil wrapped around a core in different styles like a ring, toroidal or cylindrical, and is used to control current, generate magnetic fields, filter signals by changing the electrical resistance, or even change the phase angle between two voltages.

The 2890R-44H is an example of a fixed inductor, specifically intended for use in DC motor and generator applications. It is a surface mount device (SMD) composed of two windings of wire, insulated acrylonitrile butadiene styrene (ABS) plastic, and external connecting leads.

The 2890R-44H has an inductance of 44 mH at 1 kHz, and offers a low DC resistance ratings of 0.98Ω. It also exhibits a low self-capacitance and optimized response time, making it a great choice for applications needing significant power or voltage conversion. The product is also manufactured with high quality process and material that assures a long service life.

The working principle of the 2890R-44H relies on the Faraday-Lenzi Law, which states that the voltage induced into an inductance coil is directly proportional to the rate of change of current in the inductor. This means, that when a current-changing magnetic field created by a current running through the winding of wires, it creates an output voltage, circularly proportional to the input current’s rate of change. The magnitude of the output voltage is determined by the number of turns of the wire, the pitch of the turns, and the winding core material.

The 2890R-44H is configured with two windings instead of the typical single winding in order to achieve a self-contained power transformer as an electrical circuit element, and as a result can transfer and reduce energy between circuits with different levels of voltage and current. These currents can be ripple currents, induced AC or pulsed DC currents. The 2890R-44H is designed for use in power supplies, application systems, and converter circuits in DC motors, generators, and other applications.

In conclusion, the 2890R-44H is an example of a modern fixed inductor designed for DC motor and generator applications. It utilizes advanced manufacturing process and material that ensure a long service life, and works on the principle of Faraday-Lenzi Law to induce a current-changing magnetic field that creates an output voltage of determined magnitude.
