| DVMC28 Series HIGH RELIABILITY HYBRID EMI FILTERS DESCRIPTION The DVMC series of hybrid EMI filters is operable over the full military (-55 C to +125 C) temperature range with no power derating. The DVMC EMI filter is designed to filter conducted emissions of two DVTR or one DVFL series DC-DC converters. These filters are designed and manufactured in a facility qualified to ISO9001 and certified to MILPRF-38534 and MIL-STD-883.
