Fixed Inductors are used in a wide variety of applications thanks to their strong ability to store energy in the form of magnetic fields. The 2890R-12F is a fixed inductor used in many wireless applications, such as radio antenna arrays and other RF communication systems. In this article, we’ll explore the application fields and working principle of the 2890R-12F.

The 2890R-12F has an inductance rating of 100uH and a current rating of 1.2A. It is capable of operating at frequencies ranging from 30MHz all the way up to 200MHz, and its characteristic frequency is at 169MHz. The 2890R-12F can operate efficiently at temperatures up to 150°C, making it suitable for applications in extreme environments. The inductor also features an extremely low DC resistance of 0.11 ohms.

Due to its ability to operate at higher frequencies and temperatures, the 2890R-12F is most often found in radio antenna arrays and other RF communication systems. The inductor is used in antennas to boost the signal strength, and its low DC resistance allows it to be used as a filter to reduce interference from other devices in a radio network. The 2890R-12F can also be used in a variety of other electronic circuits, such as filters, power supplies, sensing devices, and audio amplifiers.

The 2890R-12F’s working principle is based on an electromagnetism concept known as inductance. This phenomenon occurs when a certain amount of electrical energy is passed through a conductor, such as a coil. The passage of current causes the coil to become magnetized, and the magnetic field created by the coil stores the electrical energy. The magnetic field then collapses when the power is removed, releasing the stored energy back into the circuit as an electromotive force, or EMF.

The amount of energy stored and released by the coil is directly related to the inductance. The higher the inductance, the more energy is stored and released. The electromagnetic field of the 2890R-12F is strong enough to store and release a significant amount of energy, making it suitable for high-frequency applications. Additionally, its low DC resistance means that it can also be used in low-frequency applications, such as audio amplifiers.

The 2890R-12F is an ideal component to use in radio antenna arrays and other RF communication systems, as its high-frequency operation capability and low DC resistance make it a very efficient choice. Additionally, the 2890R-12F can also be used in a wide variety of other electronic circuits, thanks to its ability to store and release energy. Understanding the application fields and working principle of the 2890R-12F is essential in determining the best way to use this versatile fixed inductor.
