Product Overview
SMB6121A1-3GT30G-5-50 is a SMB straight crimp plug connector with gold-plated brass contacts and PTFE insulation. The SMB connector conforms to the requirements of MIL-C-39012 and the interface is in compliance with MIL-STD-348. The SMB provides broadband capability through 4GHz with a snap-on connector design and utilizes die-cast components in non-critical areas to provide a low-cost solution.
- Quick connect/disconnect snap-on mating reduces installation time
- SMB PCB slide-on jack allows board-to-board mounting with a low insertion force
- Annealed copper alloy crimp ferrule
- 1000Mohm minimum insulation resistance
- 50 ohm impedance
