Type HZA -55 ºC to +105 ºC
SMT Hybrid Polymer-Aluminum Electrolytic Capacitors
Load Life Test
Apply the maximum rated voltage for 10,000 hrs at +105 °C with full rated ripple current. After
Test
the test measure the capacitance, DF, DCL and ESR at +20 °C. Also measure the ESR at -40 °C and
100kHz.
∆C at 1ꢂ0Hz
DF at 1ꢂ0 Hz
Capacitance will be within 30ꢀ of the initial measured value
DF will be ≤ 200ꢀ of the initial specified value
DCL after ꢂ minute charge Leakage current will be ≤ the initial specified value
ESR at 100kHz/+ꢂ0 °C ESR will be ≤ 200ꢀ of the initial specified value
Maxꢀ 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 +105 °C without voltage. After the test, return the capacitor
to room temperature for two hours and then apply rated voltage for 30 minutes. The after test
measurements for capacitance, DF, DCL and ESR at +20 °C will meet the following.
