^electrocube METALLIZED POLYESTER PLASTIC CASE, QUICK DISCONNECT CAPACITORS 247A SERIES The 247A Séries Snubber Capacitors were designed for AC applications such as motor start, motor run, fluorescent lamp ballast and other commercial applications. A wide range of rectangular epoxy case sizes are available with quick disconnect terminals. Wrap and fill designs are also available on special order. Extended metallized polyester is used as the dielectric material. Electrocube recognizes and supports the circuit design needs for specific mounting configurations, voltages and capacitances for capacitor models not shown. Special designs can be manufactured to meet any existing or future requirement. For specific information on your product needs, contact your local sales representative or Electrocube directly. The potting material and epoxy 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.
