The FPXLF/120-20 is a 20mm x120mm rectangular ferrite core made by Abracon Corporation. It is a flat, rectangular-shaped ferrite core with a height of 20mm, a width of 120mm, and a core thickness of 2mm. It is made from Nitride oxide, manganese zinc, and nickel zinc materials. It has a split bobbin type construction for easier mounting of windings, with two mating halves. The core has an inductance range of 4.3-26.0 mH. This core is designed for high-frequency switching power supplies, common mode EMI filters, such as mobile phones and tablets, as well as other applications that require a high-frequency performance.
