Filtered D-Sub Connectors

Spectrum Control offers the industry’s most complete line of EMI filtered D-sub connectors. These connectors are available in shell sizes from 9 to 50, and come in many termination types, such as PC mount, wire wrap, solder cup and 90° PCB. In addition, we offer a wide range of filtering options, allowing you to find the right balance between performance and economy. EMI filter options include our Pi filter configuration, which provides 45-60 dB per decade slope to insertion loss curve, and our capacitive-only C filters which provide cost-effective EMI attenuation.
