SMB coaxial connector engineering reference

Family-level coupling boundary only; exact electrical performance depends on configuration. Exact example142144 only: Amphenol RF lists push-on mating, a right-angle PCB through-hole jack with solder contact termination, a brass body and contacts, and a PTFE insulator. It is a50-ohm configuration; panel mounting is Not Applicable. These construction and mounting facts do not describe all SMB parts.

Source-scoped identification facts

Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.
