Amphenol Introduces Mini 75 Ohm 45 Degree SMB Connector for 735A Cable

Amphenol introduces the new Mini 75 OHM 45 degree connector for Belden 735A. The Mini 75 OHM SMB provides broadband capability through 2 GHz. Its snap-on design utilizes the 45 degree design to help the packaging of high density printed circuit boards.

The Mini 75 OHM SMB offers snap-fit mating for quick connect/disconnect. The reduced housing allows circuit miniaturization and optimal real estate utilization. Built in accordance with requirements of MIL-C-39012 , the interface is in compliance with MIL-STD-348 and is inter-matable with industry standard for Mini 75 OHM SMB.

Key Features & Benefits:

• 75 ohm snap-on coupling for quick installation
• Same size as 50 ohm design, allowing higher density as the cable is directed away from the PCB
• Selectively plated to offer cost-reductive solution
  

Applications:

• Telecommunications
• Switching equipment
• Networking
