High Reliability
The DV-704A is a combined hybrid EMI filter and
voltage spike protection module that is operable over
the full military (-55 °C to +125 °C) temperature
range with no power derating. The DV-704A EMI
filter is designed to be used with VPT/Delta’s DVSA,
DVHF, DVTR, and DVFL series DC-DC converters to
comply with the surge requirements of MIL-STD-
704A, B, C, and D with 40 watts maximum output
power. This device also reduces the reflected noise
of the DC-DC converters to meet MIL-STD-461C
CE03 and MIL-STD-461D CE102 limits. It also
protects the DC-DC converters against the voltage
spikes specified in MIL-STD-461C CS06 and
conducted susceptibility in MIL-STD-461C CS01 and
CS02.
