931A-935D Series Metallized Polypropylene Capacitors
Capacitors Product Data Sheets
This capacitor series was designed for AC and pulsing applications. The units are rated for 135 VRMS and 67 VRMS (to 400 Hz), but may also be used for all DC applications up to 200 VDC and 400 VDC respectively.
A wide range of sizes and styles is available. You can choose from axial-lead wrap and fill in oval and round configurations or rectangular epoxy case with axial and radial leads.
Two types of dielectric material are used: metallized polypropylene and polypropylene and foil. Metallized versions are offered in all styles.
Polypropylene and foil capacitors may also be specified in all standard styles.
All capacitors feature extended foil construction and standard tin-coated copper-clad steel leads. Nickel, copper, dumet and other special leads are available.
Protective clear wrap is offered on all wrap and fill units.
The potting material and endfills of Electrocube’s capacitors meet or exceed the flammability requirements of UL94VO.
Dimensional variations for all MFD values are available with the same volume to meet your design requirements.
