Product details
Optimized for automotive electronics, the 1-1963556-4 by TE Connectivity AMP Connectors sets new standards in Thermal - Heat Sinks reliability. This AEC-Q200 qualified thermal solution addresses unique challenges in electric vehicle power systems, combining robust construction with exceptional thermal performance.The Top Mount Skived design provides precise flatness ( 0.05mm/m ) required for automotive power modules. The manufacturing process eliminates internal stresses that could lead to micro-cracking in vibration environments.Specifically engineered for IGBT and TE0600 packages, the solution manages {Power Dissipation @ Temperature Rise} under hood temperatures reaching 125 C. The thermal interface maintains integrity across 1000+ thermal shock cycles (-40 C to +150 C).The Bolt On system meets automotive vibration requirements (ISO 16750-3) while allowing for serviceability. The titanium hardware resists galvanic corrosion in wet environments.Square Pin Fins configuration delivers {Thermal Resistance @ Forced Air Flow} in turbulent underhood airflow. The staggered pin arrangement reduces boundary layer thickness by 18% compared to linear fins.For cylindrical power components, the 1.375" (34.92mm) OD variant offers crush-resistant protection. The design withstands 200N radial loads without deformation.Optimized 0.640" (16.26mm) ensures compatibility with confined spaces in electric vehicle battery management systems. The design prevents fin resonance at common engine vibration frequencies.The 5.39°C/W @ 200 LFM performance is validated under pulsating airflow conditions simulating real-world driving scenarios. The design maintains stability at airflow angles up to 30 off-axis.High-conductivity Copper ( 390 W/m K) with nickel-plated finish resists automotive fluids. The material selection meets GMW3097 chemical resistance requirements.
