FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

How does RG-316 differ from RG-174 when both have a ~2.5–2.8 mm outer diameter?
Although both are 50 Ω miniature coaxial cables with 26 AWG center conductors, RG-316 uses a silver-plated copper-clad steel conductor, solid PTFE dielectric, silver-plated copper braid, and a +200 °C FEP jacket for low loss up to 3 GHz, whereas RG-174 uses polyethylene insulation and a +80 °C PVC jacket limited to 1 GHz.
Why can RG-316 be hand-soldered or wave-soldered without melting the core dielectric?
The virgin PTFE dielectric in RG-316 has a crystalline melting point of +327 °C, preventing center-conductor migration or dielectric shrink-back when soldering SMA, SMB, MMCX, or BNC connectors. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
When should double-shielded RG-316D (RD-316 / M17/152) be specified?
Specify RG-316D when routing sensitive RF signals inside densely packed avionics or test chassis above 1 GHz, as its dual silver-plated copper braids raise shielding effectiveness from ~55 dB to > 90 dB. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
Why is a copper-clad steel (SCCS) center conductor used in RG-316?
The 7×0.17 mm steel core provides over twice the tensile breaking strength of soft copper in a miniature 26 AWG conductor, while the thick silver plating carries all high-frequency RF current via the skin effect. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
