The FCE17B25SM240 is a 25-position, B-size, filtered D-Sub socket connector from the RoHS-compliant FCE17 series. It features solder cup terminations compatible with wire up to 20 AWG and provides a filter capacitance of 680 pF for each contact to suppress EMI/RFI interference. Constructed with a tin-plated steel shell, phosphor bronze contacts, and a UL 94V-0 rated thermoplastic insulator, this connector ensures robust performance. Key electrical specifications include a 5A maximum current rating, 3000 MΩ minimum insulation resistance, and an operating temperature range of -40°C to 85°C. This connector is ideal for I/O applications in industrial, telecommunications, and data processing equipment where signal integrity is crucial.
