Cornell Dubilier Mica MCM01-009ED401J-F

The MCM01 series consists of surface mount multilayer RF capacitors made with mica or polytetrafluoroethylene (PTFE) dielectric, rated for operation from -55 °C to +200 °C with no voltage derating, and supporting voltages up to 1000 Vdc. The MCM01-009ED401J-F part corresponds to a 400 pF capacitance with ±5% tolerance, 500 Vdc rating, and a temperature coefficient of -20 to +100 ppm/°C, featuring gull-wing terminals for reduced mechanical stress. It has typical ESR of 100 pF and less than 11 mΩ at 100 MHz, is nonmagnetic, and exhibits no aging or capacitance drift with voltage, time, or frequency. The component is wave solderable, RoHS compliant, and thermally conductive, with a coefficient of thermal expansion matching FR4 PCBs. Packaging is bulk, and the part is designed for high-power RF applications including amplifiers and medical equipment.
