M-538CT

Common Mode Chokes Overview

The KEMET M-538CT is a surface-mount common mode choke from the M-500CT series, designed for signal line filtering. It utilizes a proprietary Nickel-Zinc ferrite core to provide high impedance against common mode noise. The component features a DC current rating of 100mA and a maximum DC resistance of 220mΩ. It offers an impedance of 800 Ohms at 100 MHz and maintains insulation resistance exceeding 10 MΩ when tested at 100 VDC between lines.
