The new rugged Series 945 metallized capacitors offer high-frequency operation, high current and low ESR in a miniature package. They are able to handle high surge currents without degrading thus making them an excellent electrolytic capacitor replacement. Series 945 are ideal for audio systems. This capacitor series was designed for AC and pulsing applications. The units are rated for 67 VRMS and 100 and 270 VRMS (to 100 KHz), but may also be used for all DC applications up to 200 VDC and 400 VDC respectively.
Units are available in axial-lead wrap and fill, in oval and round shapes, and in voltages of 100, 200, 400 and 600 VDC.
All capacitors feature extended foil construction and standard tin-coated copper leads.
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.
