Product details
TE Connectivity AMP Connectors's 1-1747890-1 revolutionizes Sockets for ICs, Transistors technology for next-gen automotive electronics. The robust design meets AEC-Q200 Grade 1 requirements while delivering superior electrical performance.The LGA architecture supports advanced driver assistance systems. The unique contact geometry reduces insertion force by 30% while maintaining vibration resistance.With 771 (33 x 33), the socket enables complex ECU designs. The optimized grid pattern minimizes loop inductance in power distribution networks.0.043" (1.09mm) pitch ensures reliable connections in engine control modules. The design prevents fretting corrosion under 50G vibration loads.The Gold finish provides stable contact resistance. Testing under thermal shock conditions (-40 C to 125 C) shows <3m variation.Constructed with Copper Alloy, the socket withstands harsh underhood conditions. The material maintains spring properties at 150 C continuous operation.The Surface Mount configuration simplifies assembly in tight spaces. The low-profile design fits behind instrument panels without compromising serviceability.Incorporating Open Frame, the socket prevents moisture ingress. IP67 testing confirms complete protection against dust and temporary immersion.Solder technology ensures robust connections in vibrating environments. The design exceeds USCAR-2 vibration standards for automotive connectors.The 0.043" (1.09mm) spacing accommodates heavy copper PCBs. Thermal analysis shows <10 C temperature rise at 20A current loads.Thermoplastic housing material meets flame retardancy requirements. The material achieves UL94 V-0 rating without halogen additives.With -25°C ~ 100°C range, the socket operates reliably in electric vehicle battery management systems. The design maintains performance during rapid charge cycles.
