Product Description

Hot sell SMB connetors for electronic:

The SMB name derives from SubMiniature B (the second subminiature design). RF Coaxial Connector SMB Connector Male PCB Mount Developed in the 1960's, the SMB is a smaller version of the SMA with snap-on coupling. SMB connectors conform to the requirements of MIL-C-39012, and the interface is in compliance with MIL-STD-348. Available in 50 Ω and 75 Ω impedance, the SMB provides broadband capability through 4 GHz with a snap-on connector design and utilizes die cast components on non-critical areas to provide a low-cost solution.

SMB Connector Applications:

Automotive	Automotive (GPS)	Base Stations
Cable Assemblies	Components	Instrumentation
PC/LAN	Process Controls	Radio Boards
Surge Protection	Telecom	Test and Measurement
Video Systems

SMB Connector Features and Benefits:

Broadband performance with low reflection DC to 4 GHz provides low cost connector combined with high quality.

Quick connect/disconnect snap-on mating reduces installation time.

Various plating options in nickel, gold, and tin lead. Selective plating provides corrosion resistance finish as well as good solderability characteristics.

SMB PCB slide-on plug and jack allows board-to-board mounting with a low insertion force. This is ideal for mating a high number of connectors on a pair of PCB's.
