Type HHT 175 °C, Aluminum Electrolytic Capacitor
Vibration Test
Surge Voltage Test
Mil standard 202, method 204, high frequency 20g’s
Subject the capacitors to their rated surge voltage at normal room temperature
and through a 1000 Ω ±10% resistor (except for capacitances of 2500 µF and
up, use a higher value resistor calculated as 2,500,000/C Ω ±10% where C is
the capacitance in µF). Cycle the voltage ½ minute on followed by 4½ 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 -55°C. 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.
