RF Connector SMB Connector Male Crimp Type
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. HUAXING’S 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.
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. |
