The unique high performance and long life characteristics of polyester account for the varied applications of this miniature capacitor series. A wide range of sizes and configurations are available. You can choose from axial-lead wrap and fill, oval and round shapes and rectangular epoxy case with axial and radial leads.
These 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. Please add .010” to maximum T and W dimension for protective clear wrap.
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 extended foil construction and standard tin-coated copper-clad steel leads. Nickel, copper, dumet and other special leads are available.
