After 2 minutes' application of rated voltage at 20°C
105°C, rated voltage 1000Hrs.
Within ±20% of initial value before test
150% or less than the initial specified value
Less than or equal to the initial specified value
60°C, 90 to 95%RH, No Bias, 500Hrs.
Within +50% to -20% of initial value before test
200% or less than the initial specified value
300% or less than the initial specified value
1 ESR should be measured at both of the terminal ends closest to the capacitor body.
2 Conditioning : If any doubt arises, measure the leakage current after the voltage treatment of applying DC rated voltage continuously to the capacitor for 120
minutes at 105°C.
