Cycle the voltage minute on followed by 4 minutes off during which each capacitor is discharged through the charging resistor or equal resistor. Repeat the cycles for 120 h. Post test requirements are for DCL, ESR and DF to meet initial requirements and for there to be no evidence of mechanical damage or electrolyte leakage. Storage at Low Temperature Test Test Subject the capacitor to 72 hours at -55C. After 16 hours at room temperature, measure the capacitance and DCL. C Capacitance change from the initial measurement must not exceed 10%. DCL Leakage current will meet the initial specification. Appearance No electrolyte leakage or other visible damage. The markings are to be legible.
