Product details
Optimized for automotive electronics, the SARLS-120X50MM by Sarnikon 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.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.The 1.969" (50.00mm) dimension accommodates standard automotive ECU footprints. Crash simulations confirm the design withstands 50g impacts without compromising thermal contact.With 4.724" (120.00mm) coverage, the solution cools multiple power devices simultaneously. The copper-tungsten base plate prevents thermal runaway in parallel configurations.For cylindrical power components, the 4.724" (120.00mm) OD variant offers crush-resistant protection. The design withstands 200N radial loads without deformation.Optimized 1.575" (40.00mm) ensures compatibility with confined spaces in electric vehicle battery management systems. The design prevents fin resonance at common engine vibration frequencies.High-conductivity Copper ( 390 W/m K) with nickel-plated finish resists automotive fluids. The material selection meets GMW3097 chemical resistance requirements.Natural Anodized surface provides excellent emissivity ( 0.85) for radiative cooling. The finish is resistant to road salt and brake fluid exposure.
