Engineering Bulletin Mar 07
The U32D series allows for extremely high ripple currents for applications such as inverter designs
and motor controllers. This series of capacitors offers very large capacitance of up to 2.2F and a
maximum temperature rating of 105 C which allows a high operating temperature without sacrificing
life. These capacitors are available with a variety of high current English or Metric thread terminals.
Mounting options available are a three-footed clamp or bottom stud. (A special order two-footed
clamp is also available for selected diameters.) All case size dimensions are based on inches. Custom
designs are available upon request.
