EMI Filter Modules

EMI Filters for InQor DC-DC converters

EMI Filter Modules for Industrial Applications from SynQor SynQor provides EMI filters for the InQor series DC-DC converters. All EMI filters provide >80dB differential mode attenuation and >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
