Abstract:
A monolithic polymer capacitor produced by the process comprising the steps of:vapor depositing at least two metal electrodes on polypropylene dielectric film; winding said film so as to insulate said metal electrodes from each other; applying a terminal connection to an exposed end of each said electrode thereby forming a capacitor; and curing said capacitor by steps comprising placing said capacitor in a low pressure environment, and gradually heating said capacitor to a peak temperature between about approximately 130Â° C. (403.15 K) and about approximately 200Â° C. (473.15 K) and maintaining said peak temperature for a period of time wherein said capacitor has a maximum operating temperature in excess of 120Â° C. for direct current voltages between 400 and 1200 Volts (V).
