Premium Flexible 50-Ohm RG316 Coaxial Cable with High-Temperature PTFE Dielectric and Durable FEP Jacket for Military, Aerospace, and Industrial RF Systems
The Worldpeak RG316 50-Ohm Coaxial Cable is a premium high-temperature coaxial cable engineered by Zhenjiang Worldpeak Communication Co., Ltd. to replace low-temperature options like the RG174. Featuring a compact 2.50 mm outer diameter, this flexible 50-ohm coaxial cable combines an extruded PTFE dielectric with a stranded silver-plated copper-clad steel center conductor. This specialized configuration delivers thermal stability from -55°C to +200°C. Zhenjiang Worldpeak Communication Co., Ltd. manufactures this high-performance miniature RF cable to provide excellent vibration tolerance and consistent electrical impedance, making it the top choice for complex aerospace, defense, and high-temperature industrial automation systems.
The Worldpeak RG316 50-Ohm Coaxial Cable is a highly flexible, high-temperature coaxial cable designed to maintain high signal integrity in tight spaces and harsh environments. Where standard polyethylene-insulated cables melt or fail under mechanical stress, this rugged PTFE coaxial cable ensures long-term operational performance. Zhenjiang Worldpeak Communication Co., Ltd. selects premium raw materials to manufacture the RG316 coaxial cable, ensuring precise electrical execution across a broad frequency spectrum.
The inner conductor of this flexible 50-ohm coaxial cable features a 7 x 0.10 mm stranded silver-plated copper-clad steel architecture. This stranded design provides structural fatigue resistance, allowing the miniature RF cable to withstand continuous dynamic flexing. Surrounding the conductor is a 1.52 mm extruded polytetrafluoroethylene (PTFE) dielectric that yields excellent dielectric properties and thermal endurance. The shielding system consists of a high-density, silver-plated copper braid cable that delivers a minimum of 90% coverage to suppress electromagnetic interference. The outermost layer is a 2.50 mm FEP jacketed coaxial cable housing that provides exceptional protection against oil, aggressive chemicals, and environmental moisture, making it an excellent flexible RF cable for demanding industrial field deployments.
Broad Operational Temperature Range: This high-temperature coaxial cable performs reliably between -55°C and +200°C, making it perfect for engine compartments and aerospace routing.
Vibration-Resistant Stranded Core: The 7-strand center conductor makes this flexible 50-ohm coaxial cable much more fatigue-resistant than solid-core alternatives.
High-Density Shielding Integration: The silver-plated copper braid cable layer ensures excellent signal protection and limits RF leakage in dense system compartments.
Chemical-Resistant Outer Protection: The FEP jacketed coaxial cable design resists solvents, fuels, and abrasive forces while keeping a slim 2.50 mm outer profile.
Excellent Installation Flexibility: As an ultra-adaptable flexible RF cable, it permits a tight 12 mm bend radius for effortless routing through complex mechanical structures.

To deliver the tight tolerances required for this premium RG316 coaxial cable, Zhenjiang Worldpeak Communication Co., Ltd. controls every step of the manufacturing process. Unlike conventional polyethylene options, PTFE cannot flow during standard extrusion. Instead, it requires a precise paste extrusion process followed by a controlled sintering cycle. Zhenjiang Worldpeak Communication Co., Ltd. regulates the sintering zone to a tight thermal window of plus or minus 3°C. This meticulous process ensures a uniform dielectric constant along the entire spool, preventing structural impedance variations that cause signal reflections.
Additionally, using a stranded center conductor rather than a solid core makes this flexible 50-ohm coaxial cable highly resistant to metal fatigue. Each individual 0.10 mm strand is silver-plated prior to cabling. This method keeps strand-to-strand contact resistance exceptionally low over years of movement, ensuring this high-temperature coaxial cable remains reliable where solid-core alternatives fracture. Selecting an FEP jacketed coaxial cable style over a tape-wrapped PTFE jacket also guarantees a completely uniform wall thickness, facilitating quick and secure connector installation.
Avionics Antenna Pigtails: Serves as critical flexible RF cable lines connecting blade antennas to communication modules in unpressurized aircraft bays.
Handheld Military Radios: Functions as a compact internal miniature RF cable link that withstands repeated flexing at rugged radio-to-battery hinge interfaces.
High-Temperature Industrial Sensors: Connectors for industrial level gauges and flow meters mounted directly to production vessels exceeding 100°C.
RF Precision Test Fixtures: Acts as a stable test link inside environmental chambers, ensuring accurate tracking without the structural drift common in PE lines.
Zhenjiang Worldpeak Communication Co., Ltd. provides robust B2B support, supplying international electronics manufacturers and defense contractors with highly reliable cable solutions. Every production lot of the Worldpeak RG316 coaxial cable ships with a Certificate of Conformance (CoC), validating full compliance with CE, RoHS, FCC, and UL94 flammability standards.
Zhenjiang Worldpeak Communication Co., Ltd. offers full OEM customization services for high-volume orders, including custom jacket printing and custom lengths on high-durability shipping spools. Clients can also order factory-terminated cable assemblies fitted with premium SMA, MCX, MMCX, or SSMA connectors, ensuring perfect match tolerances and fast deployment in assembly facilities.
Q: Can the RG316 coaxial cable withstand automated automated soldering setups?
A: Yes. The high-performance PTFE dielectric and tough FEP jacketed coaxial cable body easily survive automated reflow soldering profiles with peak temperatures reaching +260°C. This allow technicians to solder the miniature RF cable directly onto PCB layouts alongside standard surface-mount components without damaging the insulation.
Q: Is this flexible 50-ohm coaxial cable compatible with standard RG174 connector housings?
A: Electrically yes, but mechanically no. The outer diameter of the RG316 coaxial cable is 2.50 mm, which is smaller than the 2.60 mm diameter of an RG174. Connectors designed only for the RG174 will not grip the FEP jacket securely. Zhenjiang Worldpeak Communication Co., Ltd. recommends using connectors dimensioned specifically for the RG316 to guarantee proper strain relief.
Q: What is the primary difference between a standard RG316 and an RG316-DS cable?
A: The standard RG316 coaxial cable features a high-density single silver-plated copper braid cable shield that fits most general applications. The DS version adds a secondary shield braid to create a double-shielded layout, providing higher isolation in severe military avionics environments.
