IEC 61169-19:2011

Overview

IEC 61169-19:2011 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the sectional requirements for radio frequency (RF) coaxial connectors of type SSMB. These connectors are characterized by their 50-ohm impedance, snap-on coupling mechanism, compact size, lightweight design, and reliable electrical performance. IEC 61169-19 provides detailed rules and guidelines essential for preparing the detail specification of SSMB connectors, including dimensional data, testing procedures, and quality assessment methodologies.

This standard covers SSMB connectors designed for low power miniature applications, suitable for flexible and semi-rigid cables as well as PCB mounting. They operate efficiently at frequencies up to 3 GHz, making them ideal for various RF communication and electronic systems.
