Fixed inductors operate by storing electrical energy so that it slowly dissipates as the current flow through them. The 2890R-18G is a type of fixed inductor that has a wide range of applications in fields such as consumer electronics, automotive, and military telecommunications.

The 2890R-18G is an axially-leaded surface mount inductor that features a rated inductance of 18nH. It is composed of a Redstone magnetic core wrapped in a ferrite shell, which provides superior high-frequency performance and high current handling capabilities. The inductor also has a rated DC current of 2.3 A and a rated DC resistance of 180 mΩ. It has a maximum operating temperature of +125 °C, a self-resonance frequency of 5.8 GHz, and a temperature coefficient of reactance of -25 ppm/°C for high stability.

The working principle of a fixed inductor is based on Lenz’s Law of Electromagnetism. According to this law, when the current flows through a conductive material, a magnetic field is generated around it. This magnetic field will then create a counter-electromotive force that opposes the movement of the electrons, thus controlling the flow of the current through the circuit. To increase the inductor’s ability to limit the current, the magnetic core is wrapped in multiple layers of ferrite material to increase the inductance.

The 2890R-18G has a wide range of applications. It is used in electronic devices such as power supplies and power amplifiers where a high inductance is required. It is also used in consumer electronics such as televisions and DVD players to reduce interference from outside signals. In the automotive field, it is used in the stabilization of voltage and in the filtering of noise generated by other components. Lastly, the 2890R-18G inductor is often used in the military telecommunications sector to provide signal protection and system stability.

The 2890R-18G fixed inductor is a versatile device and has many applications in a wide variety of fields. Its superior high-frequency performance and high current handling capabilities make it a perfect choice for applications that require precise control of current flow. With its temperature coefficient of reactance, the 2890R-18G is also highly stable and reliable, making it an excellent choice for various consumer, automotive, and military telecommunications technologies.
