MGFI2012AR22KT-LF is a surface mount, 0805 RoHS compliant inductor made by Microgate. It has a flat top and bottom and is composed of a ferrite core with a copper wire. It is designed to provide a high Q value and low DC resistance and is ideal for high frequency switching applications. It has a rated inductance of 22 kO, an operating temperature range of -40°C to +85°C, and a maximum self-resonant frequency of 400 MHz. The inductance is marked as “MCF”, which stands for the value in high frequency, or millihenries. This makes it suitable for use in applications where high frequency switching is necessary, such as power supplies, amplifiers, pulse circuits, and impedance matching.
