DEVELOPMENT OF THIN ORGANIC ROLLED FILM CAPACITOR

摘要

To improve the characteristics of parylene coated foil capacitor by investigating and improving the various processes involved in manufacturing the capacitor.nTo develop a metallized parylene capacitor capable of operating over the temperature range of -55 °C to 125 °C at a rated voltage of 100 VDC, whose capacitance volume ratio is one-half that of a 50 volt metallized Mylar capacitor. Such capacitor to exhibit a dissipation factor less than 0.25%;250 me ohm microfarad minimum insulation resistance at 125 "C;temperature coefficient less than 300 ppm/°C;200% dielectric voltage withstand;less than 5% change in capacitance after life.
