Ripple current test is for evaluating the load life of capacitors working at severely adverse circumstance. The circumstance includes temperature, current, and peak voltage. The temperature is the highest ambient temperature for customer using, the current is the highest ripple current capacitors permit, and the peak voltage is capacitor applied voltage, sum of DC voltage and peak voltage of ripple. After long time test, the electrical characteristics of lower quality product will be changed. it can be checked by C/D/ESR measuring. Chroma 11800/11801/11810 Ripple Current Tester, offering series/parallel mode function to reduce test time, and digital output control function to control constant current and peak voltage output, is the best solution for capacitor quality evaluation and assurance.
