U36D

The U36D series is ideal for inverter applications requiring high ripple current capabilities. With a

voltage range through 550 volts, the number of capacitors in series can be reduced. The U36D

capacitors offer very large capacitance of up to 2.2F and a maximum operating temperature

of 85 C. 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.

Summary of Specifications

Screw terminals: high and low post, English and Metric thread.

Capacitance range: 68µF to 2.2F.

Voltage range: 6.3 to 550VDC.

Category temperature range: 40 C to 85 C.

Leakage current: 0.02CV(µA) or 5mA, whichever is smaller, after 5 minutes at 25 C.

Nominal case size (D L): D = 35mm (1.375”) to 89mm (3.500”); L = 41mm (1.625”) to

220mm (8.625”).
