Cornell Dubilier Mica MCM01-001DD270J-F

The MCM01 series consists of surface mount RF capacitors made with mica and polytetrafluoroethylene (PTFE) dielectrics, rated for operation up to 200 °C with no voltage derating and voltages up to 1000 Vdc. These capacitors feature a gull-wing terminal for reduced mechanical stress, are wave solderable, and exhibit low equivalent series resistance (ESR) and inductance for high-frequency bypass applications. The dielectric has no aging rate and maintains stable capacitance across temperature, voltage, and frequency. The part MCM01-001DD270J-F corresponds to a 270 pF capacitor with ±5% tolerance, rated at 500 Vdc, and is RoHS compliant. Its capacitance temperature coefficient is ±100 ppm/°C, and it uses a mica dielectric. The package is designed for compatibility with FR4 PCBs and has a coefficient of thermal expansion near 18 ppm/°C.
