Product details
Mill-Max Manufacturing Corp.'s 551-90-281-19-081004 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 PGA architecture supports advanced driver assistance systems. The unique contact geometry reduces insertion force by 30% while maintaining vibration resistance.With 281 (19 x 19), the socket enables complex ECU designs. The optimized grid pattern minimizes loop inductance in power distribution networks.0.100" (2.54mm) pitch ensures reliable connections in engine control modules. The design prevents fretting corrosion under 50G vibration loads.The Tin-Lead finish provides stable contact resistance. Testing under thermal shock conditions (-40 C to 125 C) shows <3m variation.200.0µin (5.08µm) thickness guarantees long-term reliability. Accelerated wear testing predicts 15-year service life in automotive applications.The Through Hole 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 0.100" (2.54mm) spacing accommodates heavy copper PCBs. Thermal analysis shows <10 C temperature rise at 20A current loads.Tin-Lead plating prevents oxidation in humid environments. Salt spray testing (96 hours) shows no measurable contact degradation.The 200.0µin (5.08µm) finish ensures reliable solder connections. The thickness is optimized for lead-free soldering processes.The Brass Alloy posts resist stress relaxation. Mechanical testing confirms <5% normal force loss after 10,000 hours at 125 C.Polycyclohexylenedimethylene Terephthalate (PCT), Polyester housing material meets flame retardancy requirements. The material achieves UL94 V-0 rating without halogen additives.
