520 Series Miniature High Voltage Capacitors
Capacitors Product Data Sheets
The unique high performance and long life characteristics of polyester account for the wide use of this miniature capacitor series. They can be used in varied applications requiring voltage ratings from 1000 to 10,000 VDC. Higher voltages are available on special order. A wide range of sizes and configurations are available. The dielectric materials used are polyester and kraft paper. You can choose from axial-lead wrap and fill in oval and round shapes.
These capacitors feature extended foil construction for 1000V units and tab construction for voltages 2000V and up with 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.
