Cornell Dubilier Mica MCM01-001ED301K-F

The MCM01 series is a surface-mount multilayer RF capacitor designed for high-power, high-temperature applications up to 200°C with no voltage derating, operating at voltages up to 1000 Vdc and capacitances from 1 to 1500 pF. It features a Gull-wing terminal for stress reduction, thermal conductivity compatible with FR4 PCBs, and a coefficient of thermal expansion near 18 ppm/°C. The part uses PTFE or mica dielectric with ultra-low dielectric absorption, no aging, and capacitance tolerances down to ±0.25 pF. It is nonmagnetic, wave solderable, and has typical ESR under 11 mΩ at 100 MHz with very low ESL for effective bypassing. The MCM01-001ED301K-F variant, with 300 pF capacitance and ±5% tolerance, confirms this series specification, though its specific terminal style and voltage rating are inferred from the part numbering system and baseline product description.
