MIL-PRF-83421/1D
Dielectric withstanding voltage (DWV): Method 301 of MIL-STD-202.
Terminal to terminal:
AC: 100 Hz ±10 Hz square wave, peak-to-peak voltage, three times dc rated voltage for 60 seconds,
minimum but need not exceed 800 V peak-to-peak.
DC: 200 percent of dc rated voltage for 60 seconds, minimum.
Insulation resistance (IR): Method 302 of MIL-STD-202. Charge time 5 minutes, maximum; however, for
capacitance values greater than 1.0 F, an additional 1 minute per F is permitted.
Terminal to terminal (dc rated voltage): See table III.
Terminals to case: 10,000 megohms, minimum.

Barometric pressure (reduced): Method 105 of MIL-STD-202, condition D (100,000 feet). 125 percent of dc
rated voltage applied. See MIL-PRF-83421 for voltage limitations.
Vibration, random (optional): In accordance with MIL-PRF-83421 when ordered with "-" replaced with "H" in the
PIN.
