The shield termination is solder as well, so the whole ground path is a solid metallic joint. ## 500 Mating Cycles — Built for Frequent Reconnects The snap-on latch holds firm once seated, and the gold-on-gold contact interface resists fretting corrosion over those cycles. One port, single-jack configuration — no multi-port ganging here.","metaTitle":"Amphenol RF 919-399J-51P MCX Jack, 50 Ohm, 4 GHz, SMT/TH","metaDescription":"Amphenol RF 919-399J-51P MCX jack, 50 Ohm, 4 GHz max, 500 mating cycles.
