Introduction:
This 20-pin SFP port PCB receptacle connector mounts directly onto host circuit boards to mate with standard pluggable transceivers. It functions inside SFC series shielding cages, which provide physical port guidance and external EMI protection. Copper alloy contact terminals feature 30u” heavy gold plating over a nickel underplate. This robust gold barrier resists surface fretting corrosion and sustains low contact resistance across frequent mating cycles. The housing is molded from high-temperature UL 94V-0 thermoplastic to resist thermal warping during SMT reflow soldering. Surface-mount leads maintain uniform coplanarity for reliable solder joint integrity on board pads. Rated from -55°C to +85°C, this high-durability receptacle suits core telecom switches, high-speed optical transceivers, and enterprise routers.
