SO-239 FLANGE CONNECTOR
Oval/Diamond 2-Hole Flange – Teflon (PTFE) Insulation
Panel-mount UHF coaxial socket with high heat resistance and gold-plated pin
COMPONENT STRENGTHS
• GENUINE TEFLON (PTFE) INSULATION: The white dielectric ensures exceptional insulating properties, minimal insertion loss and complete heat resistance, preventing deformation or movement of the centre pin during soldering.
• 2-HOLE DIAMOND FLANGE: The distinctive shape with two opposing slots allows compact, clean and ultra-stable mounting, ideal for the rear panels of radios, amplifiers or coaxial switches.
• GOLD-PLATED CENTRE PIN: The solder-cup centre terminal ensures maximum electrical conductivity, long-term resistance to oxidation and perfect solder adhesion.
Reliability and Ruggedness for Demanding RF Applications
This panel-mount SO-239 (UHF Female) connector with 2-hole diamond flange is the optimal choice for laboratories, builders and RF home-brew experts. The fully nickel-plated brass outer body resists mechanical wear and prevents corrosion, while the Teflon (PTFE) insulator allows high power handling without any risk of breakdown or short circuit. The shaped flange eliminates the side bulk of traditional square flanges, making it easier to align connectors on high-density layouts.
