SMT Hybrid Polymer-Aluminum Electrolytic Capacitors

Test

Apply the maximum rated voltage for 10,000 hrs at +105 °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.

∆C at 120Hz

Capacitance will be within ±30% of the initial measured value

DF at 120 Hz

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

Load Life Test

Shelf Life Test

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.

∆C at 120 Hz

Capacitance will be within ±30% of the initial measured value

DF at 120 Hz

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

Moisture Resistance Test

Test

Subject the capacitor to 2000 hrs at +85 °C/85%RH with rated voltage. After the test, return the

capacitor to room temperature and humidity for two hours. The after test measurements for

capacitance, DF, DCL and ESR at +20 °C will meet the following.

∆C at 120 Hz

Capacitance will be within ±30% of the initial measured value

DF at 120 Hz

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
