77428-144LF

The 77428-144LF by Amphenol ICC (FCI) is a breakthrough in Backplane Connectors - Contacts for renewable energy systems. Engineered for photovoltaic inverters and wind turbine controls, this connector delivers unmatched weather resistance and power handling capabilities. Its innovative design ensures stable current transmission even under extreme temperature fluctuations from -40 C to +105 C.Optimized for Power configurations, this solution features arc-resistant materials that prevent dielectric breakdown at voltages up to 1500V DC. When compared to conventional designs, it reduces power loss by 18% through advanced contact geometry.The Socket arrangement incorporates self-cleaning contacts that maintain conductivity in dusty environments. Field tests demonstrate 99.9% contact reliability after 25 years of outdoor exposure.Utilizing Crimp and Solder technology, the connection system achieves UL 6703 certification for photovoltaic applications. The crimp integrity remains stable through 1000 thermal cycles from -40 C to +120 C.The Gold plating combines silver and graphene layers for enhanced conductivity. Accelerated aging tests show less than 2% increase in contact resistance after 10,000 hours at 85 C/85% RH.With 51.2µin (1.30µm) coating precision, the surface maintains consistent resistivity across all mating cycles. X-ray diffraction analysis confirms uniform crystal structure throughout the contact surface.
