U32D Series Large Can Screw Terminal Capacitors

Category: Capacitors, Electronics, Nippon ChemiCon Corporation

Overview of U32D Series Capacitors

The U32D series capacitors are designed to support demanding applications that require high ripple current capabilities and an extended operating temperature range up to +105°C. These capacitors are suitable for specific high-power applications such as inverter designs and motor controllers. They are built to maintain performance without compromising lifespan, even at elevated temperatures.

Key Features

One of the significant features of the U32D series is the option for a stud mount can, which can be provided upon request. The series is based on the original 36D case sizes and follows dimensions given in inches. The capacitors are equipped with screw terminals, suitable for both high and low currents, and designed to accommodate both English and Metric measurement systems.

Specifications Summary

The U32D series capacitors offer a capacitance range from 180μF to 2.2F and a voltage range of 6.3 to 400VDC. These units function optimally within an operating temperature range from -40°C to +105°C. The leakage current is specified as the smaller of 0.02CV(μA) or 5mA after being applied for 5 minutes at a standard temperature of +25°C. The standard capacitance tolerance is rated at ±20%.

The physical dimensions of the capacitors range with a nominal case diameter from 1.375″ to 3.500″ and a length from 1.625″ to 8.625″. Their rated lifetime is 2,000 hours at +105°C with rated ripple current. This robust performance metric indicates reliability over an extended period at the maximum rated temperature.
