About the series
What it is
TNC are medium-power coaxial connectors with threaded coupling: vibration resistance, stable performance, used in wireless equipment and test benches. Standard versions operate up to 11 GHz, precision versions — up to 18 GHz.
Characteristic impedance 50 Ω, VSWR 1.3 (typical), insertion loss not more than 0.06·√f dB, insulation resistance not less than 5000 MΩ, dielectric withstanding voltage 1500 V, −55…+165 °C. Outer contact — passivated stainless steel, gold- and nickel-plated brass or tri-alloy; inner contact — beryllium copper, gold- or silver-plated brass; insulator PTFE or PEI.
