Delta DVMSA28/H-XXX High reliability hybrid emi filter Datasheet

DVMSA28 Series
HIGH RELIABILITY HYBRID
EMI FILTERS
DESCRIPTION
FEATURES
The DVMSA28 series of hybrid EMI filters is
operable over the full military (-55 °C to +125 °C)
temperature range with no power derating. The
DVMSA28 EMI filter is designed to filter conducted
emissions of DVSA series DC-DC converters.
•
•
These filters are designed and manufactured in a
facility qualified to ISO9001 and certified to MIL-PRF38534 and MIL-STD-883.
