The U32D series allows for extremely high ripple currents for applications such as inverter designs
and motor controllers. The extended temperature range allows for a high operating temperature
without sacrificing life. All dimensions are based on the original 36D case sizes which are in inches.
A stud mount can is available upon request.

Shelf Test
The following specifications shall be satisfied when the capacitors are restored to 25 C after
exposing them for 500 hours at 105 C without voltage applied. The rated voltage shall be
applied to the capacitors for a minimum of 30 minutes, at least 24 hours and not more than
48 hours before the measurements.
