Product details
The 1-1963559-4 from TE Connectivity AMP Connectors sets new benchmarks for thermal management in Thermal - Heat Sinks for consumer electronics. Designed for slim-profile devices, this solution delivers exceptional cooling performance while meeting stringent aesthetic and acoustic requirements.The Ultra-Thin Vapor Chamber design achieves just {Length} profile height while maintaining 25W/cm heat flux capacity. Compared to traditional heat spreaders, this solution reduces junction temperatures by up to 12 C.Optimized for mobile SoCs and GPU packages, the solution handles {Power Dissipation @ Temperature Rise} in 35 C ambient conditions. The thermal interface maintains performance through 1000+ power cycles.The Pressure-Sensitive Adhesive system allows for tool-less installation with consistent bond strength (3-5N/cm ). The adhesive maintains performance across -20 C to +85 C operating range.Micro-Fin Array configuration delivers {Thermal Resistance @ Forced Air Flow} in ultra-thin airflow channels. The 0.3mm fin pitch creates optimal boundary layer disruption for maximum heat transfer.For cylindrical battery cells, the 1.375" (34.92mm) OD variant provides 180 cooling coverage. The design maintains thermal contact during typical device flexing (up to 5 bend angle).Precision 0.640" (16.26mm) of just 0.5mm enables integration in sub-8mm device profiles. The nanostructured surface enhances heat transfer coefficient by 15%.The 4.96°C/W @ 200 LFM performance is optimized for low-speed fans (<5 CFM). The design maintains acoustic levels below 25dBA in typical usage scenarios.High-conductivity graphite laminate provides exceptional in-plane thermal conductivity (800 W/m K). The material is 40% lighter than equivalent aluminum solutions.
