Snap On Latched SMB RF Connector Female For Simi - Rigid RG 405
Cable
Product Description :
The SMB name derives from SubMiniature B ( the second subminiature
design ). Developed in the 1960' s, the SMB is a smaller version of
the SMA with snap - on coupling . The SMB connectors conform to the
requirements of MIL-C-39012, and the interface is in compliance
with MIL-STD-348. Available in 50Ω and 75Ω 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 .
Features & 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. |
Applications :
| • | Automotive | • | Automotive (GPS) | • | Base Stations |
| • | Cable Assemblies | • | Components | • | Instrumentation |
| • | PC/LAN | • | Process Controls | • | Radio Boards |
| • | Surge Protection | • | Telecom | • | Test and Measurement |
| • | Video Systems | | | | |
