The SMT package suits reflow assembly, and the gold body finish is compatible with standard solder pastes. The shield termination is listed as solder, meaning the ground connection is made through the body legs rather than a separate post; the board footprint must include the matching ground pads under the shield tabs. ## 500 Mating Cycles and Field-Service Durability The gold-on-gold contact interface (gold centre contact plating on both halves) resists fretting corrosion over those 500 cycles.","metaTitle":"Amphenol RF 919-384J-51P MCX Receptacle, 50 Ohm, 6 GHz, SMT","metaDescription":"Amphenol RF 919-384J-51P MCX receptacle, female socket, 50 Ohm impedance, 6 GHz max frequency, SMT, gold body, 500 mating cycles, bulk.
