RG-196A/U Miniature Coaxial CableMIL-C-17 · 50 Ω ± 2 Ω · Ø 2.03 mm · 30 AWG (7×0.10) SCCS · Solid PTFE · SPC braid · +250

Q: How does RG-196A/U compare to RG-178B/U?

Both cables share the exact same 30 AWG (7×0.102 mm) silver-plated copper-clad steel center conductor, 0.86 mm solid PTFE dielectric, and 38 AWG silver-plated copper braid; RG-196A/U uses a fused white PTFE tape jacket rated to +250 °C, while RG-178B/U uses an extruded brown FEP jacket rated to +200 °C.

Q: When should RG-196A/U be chosen over RG-316 or RG-188A/U?

Choose RG-196A/U when routing space or weight is critical—its 2.03 mm diameter and 8.9 kg/km mass are roughly half the weight of RG-316/RG-188A/U, fitting subminiature MMCX, SSMB, and MCX board 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.

Q: What is the maximum voltage rating of RG-196A/U?

Despite its 0.86 mm dielectric diameter, the high dielectric strength of virgin PTFE allows RG-196A/U to carry 750 V rms continuous working voltage and pass a 1.5 kV rms AC withstand test. 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.

Q: For even smaller medical ultrasound probe bundles, what cable is recommended?

For 36 AWG to 46 AWG multi-channel catheter, endoscope, and ultrasound probe bundles, specify our Micro-Coaxial Cable for Medical and Precision Equipment. 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.
