RG316D 50 Ohm Coaxial Cable Double Shielded MIL-DTL-17 Compliant Cable with FEP Jacket
RG316D M17/113-RG316D is a MIL-DTL-17 qualified 50 Ohm coaxial cable featuring double silver-plated copper braid shielding for enhanced EMI protection compared to standard RG316. This low loss RF cable utilizes a 7/0.17mm silver-plated copper-clad steel (SCCS) stranded conductor and PTFE dielectric, delivering reliable signal transmission up to 3 GHz with 96.5 pF/m capacitance and 70% velocity of propagation. The double silver-plated copper braid provides superior shielding effectiveness in electrically noisy environments, while the FEP outer jacket at 2.9mm offers excellent chemical resistance, UV stability, and thermal performance from -55°C to +200°C. With 1200V RMS operating voltage and NSN assigned for government procurement, RG316D is the preferred choice for telecommunications infrastructure, radar systems, and defense electronics where signal integrity and interference rejection are critical.

A: RG316D operates efficiently from DC up to 6 GHz, making it suitable for VHF through C-band applications. Some manufacturers specify 3 GHz maximum operating frequency.
Q: What is the temperature range?
A: Continuous operation from -55°C to +200°C, enabled by PTFE dielectric and FEP jacket construction.
Q: What is the voltage rating?
A: 900V RMS to 1200V RMS maximum operating voltage.
Q: What type of conductor does RG316D use?
A: 7/0.17mm silver-plated copper-clad steel (SPCCS) stranded conductor with 7 strands of 0.17mm.
Q: What is the outer diameter?
A: 2.9mm to 2.93mm including FEP jacket.
Q: What is the capacitance?
A: 96.5 pF/m with 70% velocity of propagation.
Q: What is the bend radius?
