DC EMI Filter Modules

EMI Filters for InQor, Mil-COTS and Hi-Rel DC-DC converters

EMI Filter Modules for Industrial and Military Applications from SynQor SynQor provides EMI filters for the InQor, MIL-COTS and Hi-Rel series DC-DC >36dB or >60dB common mode attenuation (model dependent) and include stabilizing bulk capacitors and damping resistors.

Note 1 While the passive filters can withstand these long-duration surge voltages, the surge voltage will be passed to the filterís load. Care should therefore be taken to make sure that the load will also be able to withstand any applied surges. The transient suppression filters block surges of either polarity, as specified in their data sheets

Note 1 T and T6 filters feature enable pass-through, transient suppression, soft-start and reverse polarity protection circuitry in addition to passive filter components.
Note 2 R filters feature reverse polarity protection circuitry in addition to passive filter components.
Note 3 While the passive filters can withstand these long-duration surge voltages, the surge voltage will be passed to the filterís load. Care should therefore be taken to make sure that the load will also be able to withstand any applied surges.
