Useful Life
The U37X series is the longest life version of the U37 grade series and is specifically designed to
provide the ripple current capability and long life required for high reliability inverter applications. The
U37X has an endurance rating of 15,000 hours at ؀85؇C with the rated ripple current applied. The
useful life can exceed 175,000 hours at ؀40؇C and 2.1x the ripple current. These capacitors are
available in a variety of high current English or Metric thread terminals. Mounting options include a
three-footed clamp or bottom threaded stud. Custom designs are also available.
