MCX Snap-On Jack for 6 GHz Signal Paths
The polytetrafluoroethylene (PTFE) dielectric keeps the impedance consistent through the band. This is a surface-mount part, terminated by solder reflow to the board — no through-hole, so the RF launch sits on the top layer and the ground plane references the pad pattern underneath.
50 Ohm System Fit and 6 GHz Ceiling
The 50 Ohm impedance matches the standard RF system impedance for wireless infrastructure, test equipment, and instrumentation — no impedance transformer needed at the interface. The 6 GHz frequency ceiling covers L-band, S-band, and mid C-band applications; the connector is usable up to that limit with the VSWR and insertion loss typical of an MCX interface. The 500 mating cycles rating reflects the snap-on design: the spring-loaded outer contact wears with each mate, but 500 cycles supports repeated test connections or field-disconnect scenarios without contact degradation.
SMT Termination and Tape & Reel Packaging
The shield and centre contact both terminate by solder — the shield ring solders to the board ground pads, the centre pin to the RF trace. Surface-mount termination keeps the component profile low and eliminates the need for a plated through-hole. The Tape & Reel and Cut Tape packaging options suit both high-volume pick-and-place lines and small prototype runs.
Comparison: 919-382J-51P Bulk Variant
The 919-382J-51P is electrically identical — same 50 Ohm MCX female socket, same 6 GHz ceiling, same gold-over-brass body and beryllium copper contact. For a high-volume reflow line, the Tape & Reel variant feeds directly into the feeder; for a manual or low-volume build, the Bulk variant avoids the tape handling step.
