Load life
(after application of the rated
voltage for 2000 hours at 125°C)
After 1000 hours no load test, leakage current, capacitance and tanҜare same as load life value.
The measurement shall be performed at 20ƆC by the KS C 6503 clause 5.1.
Shelf life (at 105°C)
The following specifications shall be satisfied when the capacitors are restored to 20ƆC
after exposing them at 250ƆC for 30 seconds.
