SR-141C-SP is a premium 0.141" (3.58mm) 50-ohm semi-rigid coaxial cable engineered for high-performance RF and microwave applications in magnetically sensitive environments like MRI/NMR systems, scientific instruments, and aerospace modules, featuring fully non-magnetic materials (no ferromagnetic alloys) throughout the center conductor, dielectric support, and silver-plated copper outer conductor that delivers 10-15% lower insertion loss than bare copper shields above 6 GHz through superior skin effect conductivity, with 0.141" diameter providing optimal balance between ultra-compact 0.086" routing and lower-loss/higher-power 0.250" trunk lines, solid silver-plated copper center conductor, solid PTFE dielectric (70% VOP), precision ±1.0Ω impedance control maintaining VSWR <1.25:1 to 12.4 GHz (extendable to 18 GHz), >100 dB shielding effectiveness, -55°C to +125°C rating, and excellent vibration resistance for long-term reliability in medical, defense, and research production assemblies.
Fully non-magnetic construction – Safe for MRI/NMR/scientific applications near strong magnets
Silver-plated copper outer conductor – 10-15% lower RF loss vs bare copper shields above 6 GHz
0.141" semi-rigid geometry – 0.075'' minimum bend radius, higher power than 0.086" semi-rigid cables
50-ohm ±1.0Ω impedance control – VSWR <1.25:1 DC-12.4 GHz typical
Low Attenuation – 0.416 dB/ft @ 10 GHz, 0.596 dB/ft @ 18 GHz
PTFE dielectric – 70% VOP, -55°C to +125°C, low outgassing for vacuum use
RoHS compliant – Meets global manufacturing standards
OEM/ODM ready – Low MOQ, custom lengths/pre-formed assemblies from CAD

Q: What specific materials make SR-141C-SP semi-rigid cable non-magnetic?
A: This 0.141'' semi-rigid cable uses non-magnetic silver plated copper for conductor and shield. No nickel-iron, steel, or other ferromagnetic materials. Verified <0.1% magnetic attraction in 1.5T fields.
Q: How much performance improvement does silver plating provide vs tinned copper?
A: Silver-plated copper shield reduces surface resistance 15-25% above 6 GHz due to optimal skin effect conductivity. Measured improvement: 0.05-0.12 dB/ft lower attenuation at 8-12.4 GHz.
Q: When should I choose 0.141" vs 0.086" non-magnetic semi-rigid cable?
A: SR-141C-SP for longer runs (>12"), higher power (>25W CW @ 5 GHz), or tighter loss budgets. SR-086C for maximum packaging density in ultra-compact modules where 3-5 dB extra loss is acceptable.
Q: Can you manufacture custom pre-formed assemblies?
A: Yes, from your 2D/3D CAD files. Minimum bend radius 0.075". Lead time typically 5-7 business days with VSWR/IL test data. Phase-matched sets available for multi-channel systems.
Q: What are your MOQ and lead times for production?
A: Low MOQ: 10 assemblies minimum for custom work. Stock lengths ship same/next day. 100+ pcs production: 2-3 weeks. Volume pricing available for qualified OEM programs.
