SR-141C-TP is a 0.141" (3.58 mm) 50-ohm semi-rigid cable built with non-magnetic materials and a tinned copper outer conductor, designed for RF and microwave systems that operate near strong magnetic fields and require reliable, production-friendly assembly. The non-magnetic construction minimizes disturbance to MRI/NMR magnets and other sensitive fields, while the tinned copper shield offers a proven balance of good high-frequency performance, excellent solderability, and corrosion resistance for long-term stability. With its 0.141" diameter, solid silver plated copper inner conductor, PTFE dielectric, and controlled impedance, SR-141C-TP provides a practical combination of moderate loss, solid power handling, and robust mechanical strength for medical, aerospace, industrial, and test/measurement applications.
Non-magnetic construction – Cable materials chosen to avoid ferromagnetic alloys, suitable for magnet-sensitive environments.
Tinned copper outer conductor – Reliable RF performance with excellent solderability to connectors, housings, and ground planes.
0.141" 50-ohm semi-rigid design – Higher power capability and lower loss than 0.086" transmission lines, still compact enough for dense modules.
PTFE dielectric – Stable electrical properties over wide temperature ranges, suitable for lab, medical, and industrial use.
Good shielding effectiveness – Solid metal shield helps reduce leakage, EMI, and crosstalk in multi-channel systems.
Formable semi-rigid construction – Can be bent and pre-formed to defined shapes, maintaining routing under vibration and thermal cycles.
OEM/ODM friendly – Available as bulk cable or custom assemblies with low-to-medium minimum order quantities.

MRI / NMR equipment – Non-magnetic RF interconnects between coils, amplifiers, and system racks where magnetic cleanliness and practical assembly are both important.
Scientific and research systems – RF links in spectroscopy setups, accelerator facilities, and magnet-based experiments needing stable cables near strong fields.
Aerospace and defense modules – Semi-rigid cable runs inside radar, EW, and communication units where non-magnetic materials, reliability, and serviceable solder joints are required.
Medical RF devices – RF paths in imaging, therapy, and monitoring equipment that must combine non-magnetic behavior with robust mechanical performance.
Telecom and datacom hardware – Internal semi-rigid connections in base stations, microwave radios, and RF front-ends where 0.141" is a good fit between loss and size.
Test and measurement assemblies – Custom semi-rigid test cables, fixtures, and instrument jumpers that benefit from easy soldering and repeatable shaping.
Custom pre-formed harnesses – Multi-cable assemblies with defined bends and lengths for faster production line installation and consistent electrical behavior.
Q: How does SR-141C-TP differ from SR-141C-SP?
A: Both are 0.141" non-magnetic semi-rigid cables, but SR-141C-TP uses a tinned copper shield, while SR-141C-SP uses silver-plated copper. The tinned version typically offers slightly higher loss at very high frequencies but better cost balance and very good solderability for production.
Q: When would I choose SR-141C-TP instead of the silver-plated version?
A: SR-141C-TP is a strong choice when you need non-magnetic behavior and solid RF performance, but ultra-low loss is not the top priority, for example in moderate-length runs, lower-frequency bands, or cost-sensitive designs where manufacturability and reliability matter most.
Q: Is SR-141C-TP suitable for use around MRI or other strong magnets?
A: Yes, it is designed as a non-magnetic semi-rigid option, so it minimizes attraction and field distortion compared with cables that use ferromagnetic metals in their structure.
Q: Can SR-141C-TP be supplied as custom pre-formed assemblies?
A: Yes. It can be provided as straight lengths or as pre-formed assemblies built to your drawing, with specified lengths, bend radii, angles, and connector types on each end.
Q: What should buyers specify when requesting SR-141C-TP?
A: Include semi-rigid cable type (SR-141C-TP), required quantity, lengths, connector series and genders, target frequency range and approximate power level, any non-magnetic or environmental requirements, and whether you need straight or pre-formed assemblies and test data (e.g., VSWR, insertion loss, or phase matching).
