Useful Life

Useful Life for aluminum electrolytic capacitors

By entering the usage conditions, it is possible to easily calculate the useful life of the capacitor.

Precautions for Use
  1. Useful life shall indicate the end of the life time without exceeding the specified failure rate. It's generally known that Aluminum Electrolytic Capacitors have wear-out failure mode with gradual deteriorate of the electrical parameters and should have large number of the failure rate at the end of life. The useful life time is specified by a certain failure rate. It's not a guaranteed specification.
  2. Generally the maximum life time is 20 years (175,200 hours) considering sealing material deteriorate. When a longer life time is required for your application, please consult us.
