No suffix – bare copper

TM – Tri-alloy plated

TP – Tin plated

NTD Cable Low Loss Semi-Rigid Coaxial Cable

NTD series semi-rigid cable provides lower loss, lighter weight, higher power handling capacity, and less temperature-related phase change than competitor’s. It features a silver-plated copper center conductor, low-density PTFE dielectric instead of solid PTFE, and a solid copper tube outer conductor and uses the same solder-on connectors as standard semi-rigid cable. Typical applications include test setups, interconnection, and instrumentation. It is available for fast delivery as cable and OEM is welcome. There is no minimum order quantity requirement.

Features

• Low loss
• Lightweight
• Higher power handling
• Wide temperature operating range
• Less temperature-related phase change
• No core extension after temperature cycling
• Plenty connector options

Typical Applications

• Aerospace
• Plate-to-plate connection
• Card interconnection
• Cabinet jumpers
• Airborne radar
• Missile systems
• Phased array radars
• Feed networks
• Instrumentation
