IEC 61169-1-3:2026 pdf download,Radio-frequency connectors – Part 1-3: Electrical test methods – Surge withstand – Surge protective devices built in a coaxial connector – Performance requirements and testing methods.
IEC 61169-1-3:2026 is an international standard that specifies performance requirements and electrical test methods for surge protective devices (SPDs) integrated into coaxial radio-frequency (RF) connectors. Published in April 2026, it belongs to the IEC 61169 series focusing on RF connectors, addressing surge withstand capabilities for telecom and signalling networks.
It applies to systems with nominal voltages up to 1,000 V AC or 1,500 V DC, protecting equipment from lightning-induced transients and other sudden overvoltages by diverting surge currents safely. The standard covers four main SPD types: gas discharge tube, ΒΌ wavelength short stub, flash-off gap, and hybrid designs.
Key content includes design criteria, essential performance parameters, and rigorous test procedures. It defines limits for sparkover voltage, insertion loss, return loss, insulation resistance, and impulse durability, ensuring minimal RF signal disruption while delivering reliable surge protection. Tests verify both initial performance and post-surge functionality under repeated transient stress.
As the first dedicated standard for built-in coaxial SPDs, it unifies global technical specifications for manufacturers, test labs, and network operators, enhancing reliability and safety of RF systems exposed to harsh electrical environments.
