Fixed inductors are electrical components designed to store energy in the magnetic field when electric current is flowing. They are most commonly used in filters, timing circuits, oscillator circuits, and power supplies. ELJ-FC2R2KF is one type of fixed inductor manufactured by Panasonic, which is widely accepted in the market for its reliable performance. This article will provide a comprehensive discussion on the application field and working principle of the ELJ-FC2R2KF fixed inductor.

The ELJ-FC2R2KF fixed inductor is made with ferrite core material and used for applications where the inductance value needs to be kept constant. Its operating temperature ranges from -40°C to 85°C, and its nominal inductance value is 2.2µH. The inductor features excellent high frequency characteristics, low profile, and an exceptional Q factor.

The ELJ-FC2R2KF fixed inductor is mainly used in power applications, such as DC-DC converters, frequency converters, etc. The device can also be used for AC applications, such as filtering noise and harmonics, which is advantageous in protecting sensitive components of various types of equipment. Moreover, the device is also often employed in analog and digital circuits, including audio amplifiers, signal processors, radio communication systems, etc.

The working principle of a fixed inductor is based on Faraday\'s law, which states that the magnetic flux, Φ, is linearly related to the applied current, i.e., Φ = Lia, where Lia is the inductance. When the current flowing through the inductor is altered, the magnetic flux will also change accordingly, resulting in an opposing electromotive force that can maintain the current. In other words, this force, also known as the “back EMF”, works to counter the applied current, resulting in inductance. This also explains how fixed inductors can be used as filters and other components.

The ELJ-FC2R2KF fixed inductor is designed with a ferrite core material, which ensures high reliability and compatibility with different types of circuits, making it an ideal solution for a variety of applications. The device is characterized by excellent high frequency characteristics, low profile, and an exceptional Q factor, as well as an operating temperature ranging from -40°C to 85°C. Furthermore, it features a nominal inductance value of 2.2µH.

In conclusion, ELJ-FC2R2KF fixed inductor is a highly versatile component designed for a number of applications, ranging from power conversion and rectification to AC filtering and signal processing.
