MIL-C-25/6E
NOTE: Permissible operating voltages, while based on incomplete data are the capacitor suppliers' best estimate to
provide a life expectancy of 8,800 hours of continuous operation at higher ambient temperatures. Longer life can be
expected by operation at voltages lower than indicated on the curve: For example, a life expectancy of 44,000 hours
may be obtained by operation at 70 percent of the voltage determined by use of this curve. Also, a life longer than
8,800 hours may be expected at the voltage determined by use of this curve if the high ambient temperature prevails
for only a portion of the whole operating time.
