MIL-DTL-38449D
all pins (tied together) and the case for a period of 1 minute. Leakage current of 500
microampere or greater shall constitute failure.
3.7.5 Transients and high frequency noise susceptibility.
3.7.5.1 Transients. The units shall be capable of withstanding voltage transients in accordance
with the paragraph entitled, Voltage Transients, and Figure entitled, Transient Surge DC Voltage
Step Function Loci Limits for Category C Equipment, of MIL-STD-704. The transient may
consist of a positive pulse applied to the power input terminals of 80V dc for a duration of 0.04
second, or an equivalent voltage and time function, and as specified herein.
3.7.5.2 Transient sensitivity. The units shall not advance from READY to CONTACT or from
CONTACT to DISCONNECT when subjected to voltage and corresponding time factors in the
"shall not operate" range of Figure 2.
3.7.5.3 High frequency noise susceptibility. The units shall not advance from READY to
CONTACT or from CONTACT to DISCONNECT when the power and signal leads are
subjected to high-frequency noise bursts (broad band RF) for a maximum time duration of 1
millisecond and a minimum voltage amplitude of 200V peak-to-peak. These bursts are generally
associated with the actuation of reactive solenoids.
3.7.6 Ripple. The units shall be capable of proper operation as specified herein when subjected
to the ripple specified in MIL-STD-704, paragraph entitled, Ripple.
3.7.7 Life. The unit shall be capable of being cycled 50,000 times in accordance with 4.4.8
without malfunction or failure of any type.
3.7.8 Environmental. The amplifier shall withstand the following environmental conditions as
specified in Section 4 and MIL-STD-810 with no deterioration, deformation, leakage, corrosion,
or malfunction:
a. High temperature
b. Low temperature
c. Fungus
d. Salt fog
e. Humidity
f. Shock
g. Immersion (leakage)
h. Vibration.
3.7.9 Operating conditions.
