ETC DVMH28

DVMH28 Series
HIGH RELIABILITY HYBRID
EMI FILTERS
DESCRIPTION
FEATURES
The DVMH series of hybrid EMI filters is operable
over the full military (-55 °C to +125 °C) temperature
range with no power derating. The DVMH EMI filter
is designed to filter conducted emissions of two
DVHF or one DVTR series DC-DC converters.
·
·
These filters are designed and manufactured in a
facility qualified to ISO9001, compliant to AS9000,
and certified to MIL-PRF-38534 and MIL-STD-883.
