The new 926 Series IGBT Snubber Capacitors were designed for AC and pulse applications. A wide range of rectangular epoxy case sizes are available with tinned copper lugs. Wrap and fill design is also available on special order.
Extended metallized polypropylene is used as the dielectric material.
Electrocube recognizes and supports the circuit design needs for specific mounting configurations, voltages and capacitances for snubber 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 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.
