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 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.
