RF Interconnect Field Note — 619540-1 SMA Jack
The 335 V voltage rating is the breakdown limit between center and outer conductor at sea level; in practice the system's power handling is limited by the 3 GHz bandwidth and the cable's own rating.
Lifecycle and Sourcing — Obsolete Status
The TE Connectivity 619540-1 is listed as Obsolete.
Termination and PCB Fit
The shield termination is solder — not a press-fit or solderless ground tab — so the ground plane connection relies on a clean solder fillet around the four ground legs. The single-port design mates with a standard SMA plug; the threaded coupling requires a mating connector with the corresponding male thread.
