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-STD704A, 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.
