Load Life Test
Test
∆C at 120Hz
DF at 120 Hz
Apply the maximum rated voltage for 4,000 hrs at +125 °C with full rated ripple current. After
the test measure the capacitance, DF, DCL and ESR at +20 °C. Also measure the ESR at -40 °C and
100kHz.
Capacitance will be within ±30% of the initial measured value
DF will be ≤ 200% of the initial specified value
DCL after 2 minute charge Leakage current will be ≤ the initial specified value
ESR at 100kHz/+20 °C ESR will be ≤ 200% of the initial specified value
Max. ESR at 100kHz/-40 °C Case Code C : 2.0 Ω; Case Code D : 1.4 Ω; Case Code X : 0.8 Ω;
after Load Life test Case Code F : 0.4 Ω; Case Code G : 0.3 Ω
Shelf Life Test
Subject the capacitor to 1000 hrs at +125 °C without voltage. After the test, return the capacitor
