Description
Belden 1673A TIN is a conformable 50 Ohm microwave coax for microwave and other high frequency applications. It uses an RG-402 construction with a 19 AWG solid SCCS - Silvered Copper Covered Steel conductor and PTFE - Polytetrafluoroethylene insulation. This unjacketed coax has a nominal overall cable diameter of 0.138 in (3.51 mm) and an operating temperature range of -70°C to +200°C. Shielding is a dual-layer design combining a 100% bare copper tape and a 100% tinned copper (TC + Tin Filled) braid.
Belden 1673A TIN Key Features
- Conformable coax construction listed as hand formible for routing and forming in tight layouts.
- RG-402 / RG type 402 coax design with a nominal characteristic impedance of 50 Ohm.
- 19 AWG solid SCCS - Silvered Copper Covered Steel conductor with a nominal conductor diameter of 0.036 in.
- PTFE - Polytetrafluoroethylene insulation with white color code and a nominal insulation diameter of 0.116 in (2.95 mm).
- Special shield construction with layer 1 outer shield: tape, bare copper (BC), 100% coverage, plus layer 2 outer shield: braid, tinned copper (TC + Tin Filled), 100% coverage.
- Unjacketed design (outer jacket: no jacket) with a nominal overall cable diameter of 0.138 in (3.51 mm).
- Operating temperature range of -70°C to +200°C; UL temperature: 105°C.
