MIL-PRF-83726/30J
Power interrupt: 500 microseconds. (Transient and power loss specifications are based on a
maximum duty cycle of 1/50.)
Operating current: 150 mA maximum at 25C.
INPUT REQUIREMENTS:
Input voltage range: 20 V dc to 30 V dc. (Minimum high temperature test 21 V dc, minimum
continuous current test 23.5 V dc.)
Duty rating: Continuous.
Polarity protection: The timer shall be inoperative during, and undamaged by, reversal of the polarity
of the operating voltage.
OUTPUT REQUIREMENTS: (At +25C unless otherwise specified.)
Configuration: DPDT.
Life: See table I.

ELECTRICAL REQUIREMENTS:
Transients: In accordance with MIL-STD-704 for 28 volts dc system (figure 11).
Spike:
Self-generated: 50 volts maximum.
Spike transients: 600V, 10 microseconds maximum.
Susceptibility: + 80V maximum; -600 V maximum.
Electromagnetic interference: In accordance with MIL-STD-461(methods CS101, CS114, RS101,
and RS103) for PIN's with suffix letter W. (EMI test limits will not be exceeded during the timing
interval or when continuously energized under steady-state conditions in accordance with the EMI
test of MIL-PRF-83726.)
Insulation resistance: 1,000 megohms at 500 V dc at sea level, and 100 V dc at 80,000 feet between
each pin and case. (Terminals X1, X2 and D1, D3 must be connected together during this test.
Insulation resistance is measured between all mutually insulated terminals and between all terminals
and case.)
