voltage for 2000 hours at 105°C)
Shelf life (at 105°C)
±20% at 120Hz, 20°C
Capacitance > 1000μF : tanδincreases by 0.02 for each 1000μF from below value.
After 1000 hours no load test, leakage current, capacitance and tanδare same as load life value.
Ø5, 6.3 and Ø8 products are for 1000 hours
WV≦100
I = 0.01CV or 3μA whichever is greater (after 2 min)
I = 0.03CV or 4μA whichever is greater (after 1 min)
WV >100
I = 0.02CV+15μA (after 5 min)
