Product details

MCX Jack for 4 GHz Signal Paths — 50 Ohm, Snap-On, 500 Cycles

Dual Mounting — Surface Mount and Through Hole in One Footprint

This jack accepts both Surface Mount and Through Hole termination — an unusual dual-option that lets you solder the shield to the board surface while the centre contact goes through a plated hole. 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.
