5646445-1

The 5646445-1 by TE Connectivity AMP Connectors redefines performance standards in Backplane Connectors - Hard Metric, Standard for automotive electronics. Optimized for next-generation vehicle architectures, this connector system addresses the unique challenges of automotive EMC requirements and thermal management. Its innovative design supports 48V mild hybrid systems and autonomous driving sensor networks with unmatched reliability.Featuring Receptacle, Female Sockets configuration, this automotive-grade connector exceeds USCAR-2 vibration specifications. The dual-beam contact design maintains electrical continuity during 15G vibration exposure.The E 25 mechanical design incorporates CPA (Connector Position Assurance) features that prevent accidental unmating. This safety-critical feature meets ISO 8820-3 requirements for automotive applications.With 200 available circuits, this connector supports domain controller architectures. The optimized layout provides 100MHz bandwidth with less than 3% impedance variation across temperature extremes.The All configuration enables smart power distribution with integrated current sensing. Power contacts feature 85A continuous rating at 105 C ambient temperature.The 0.079" (2.00mm) spacing achieves automotive-grade density while maintaining 2.5mm creepage distance. The high-temperature LCP housing material withstands 150 C continuous operation.The 8 contact arrangement provides balanced mechanical stress distribution. This design passes 5000 thermal cycles between -40 C and +125 C without performance degradation.Developed for Board Edge, Through Hole, Right Angle installation in automotive ECUs, this connector features anti-walk PCB retention. The reinforced solder joints withstand 10,000 thermal cycles per AEC-Q200.The Press-Fit process creates reliable connections that pass 85 C/85% RH testing for 1000 hours. The crimp-style contacts maintain pull-out force above 50N after environmental aging.The Gold plating system provides superior performance in sulfur-rich environments. Testing shows contact resistance remains stable after 1000 hours of mixed flowing gas exposure.With 30.0µin (0.76µm) gold deposition, the contacts achieve 50% better wear resistance than standard automotive requirements. This coating thickness optimizes friction characteristics for sealed connectors.
