Cosmtec Products

 
Product Application
 
SMB (Subminiature version B) Connectors have a snap-on coupling and are available for 50 OHM and 75 OHM offering electrical performance from DC to 4GHz (50 OHM) and from DC to 2GHz (75 OHM). SMB Styles are available for flexible, conformable and semi-rigid cables. SMB series are available for mounting to printed circuit boards employing through-hole soldered, through-hole press-fit and surface mount technique (SMD). Solder, crimp and clamp modes are used to assemble SMB connectors to cables. Applications include Base Stations, Automotive, GPS, Telecom Cable Assemblies, Components, Instrumentation PC/LAN, Process Controls, Radio Boards Surge Protection, Test and Measurement Video Systems.
 
SMB & SMC are all the same type but with different coupling system.
SMB has a snap-on coupling that is rapid but secure connections.
SMC has a threaded coupling for vibration environments.
