The Series 500 are cost effective, highly reliable EMI filtered D-Subminiature connectors that feature a .318" footprint for 90 degreee PCB connectors and a low profile housing on straight PCB connectors. Series 500 filtered D-Subs are "drop-in" replacements for standard unfiltered D-Sub connectors.
The ability of these filters to achieve EMI filtering within the smaller footprint is the result of technical advances in ceramic capacitors. Series 500 connectors use tubular capacitors for high performance EMI filtering. Quality features for these connectors include board lock mounting, metal front shells and gold plated contacts.
Series 500 capacitive filtered D-Sub connectors are an ideal solution to FCC/EC/VCCI emissions problems. These connectos are designed to protect equipment from external EMI noise and eliminate system glithces.
