EVALUATION - DEVELOPMENT OF MIL-C-14157B CAPACITORS
Abstract
The following types of capacitors performed exceptionally well in the 1000 hour test, and the capacitance and dissipation factor essentially did not change: (1) second control test Bendix (E-200) capacitors, (2) control and irradiated units with Samica dielectric film impregnated with monoisopropylbiphenyl dielectric fluid, and (3) control and irradiated units with Samica dielectric film impregnated with C-oil resin. The control and irradiated units with Samica dielectric film and a silicone resin impregnant had the best survival rate; however, changes in capacitance, dissipation factor and insulation resistance in the irradiated group were excessive. Isocyanate treated Mylar units impregnated with monoisopropylbiphenyl failed in less than 30 hours. All but one of the modified linear polyester dielectric film units failed prior to the end of the test. (Author)
