Product details

MCX Snap-On Receptacle for 6 GHz Signal Paths

Rated to 6 GHz, this connector covers the sub-6 GHz bands used in Wi-Fi, Bluetooth, and cellular IoT front-ends, with the PTFE dielectric keeping the impedance stable across the band.

Surface-Mount Footprint and Board Assembly

This MCX receptacle uses surface-mount termination for both the signal and the shield — the centre contact solders to a PCB pad, and the shield legs solder to the ground plane. 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.

Frequently asked questions

What is the impedance of 919-384J-51P?

The impedance is 50 Ohm, the standard for RF signal paths in wireless and telecom equipment.

What is the mounting type for 919-384J-51P?

It is a surface-mount receptacle — the centre contact and shield legs solder directly to PCB pads, suited for reflow assembly.
