U37F
The U37F series is a general purpose, screw mount U37 grade series specifically designed to provide
the ripple current capability and long life required for high reliability inverter applications.The U37F
has an endurance rating of 5,000 hours at 85 C with the rated ripple current applied. The useful life
can exceed 150,000 hours at 40 C and 1.5x 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.
