Product details
TE Connectivity AMP Connectors's 8-1542003-4 redefines thermal solutions in the Thermal - Heat Sinks segment, specifically developed for industrial automation systems. This thermally-optimized design incorporates innovative features that address heat management challenges in harsh operating conditions while ensuring long-term reliability.The Board Level Vertical configuration enables space-efficient thermal management in control cabinets. Unlike conventional top-mount designs, this orientation reduces PCB warpage risks by 30% during thermal cycling.Designed for power modules and TO-247 packages, the solution handles {Power Dissipation @ Temperature Rise} with margin for overload conditions. The thermal interface maintains stability across 50,000+ power cycles.The Clip attachment system allows tool-less installation, reducing assembly time by 40% in high-volume production. The patented spring mechanism maintains consistent pressure despite material creep.Rectangular Angled Fins direct airflow along predetermined paths, achieving {Thermal Resistance @ Forced Air Flow} in constrained ducts. The aerodynamic profile reduces audible noise by 5dB at high airflow rates.For cylindrical components, the 1.375" (34.92mm) OD variant offers 360 cooling coverage. The press-fit installation ensures consistent thermal interface pressure.The 0.357" (9.07mm) is calibrated for optimal performance in both horizontal and vertical orientations. Finite element analysis confirms no performance degradation at 45 mounting angles.Independent testing verifies 7.22°C/W @ 200 LFM remains stable despite dust accumulation (per IEC 60068-2-68). The fin spacing prevents particulate clogging common in industrial environments.The 13.40°C/W specification makes this solution ideal for fail-safe cooling in fan-less designs. The thermal mass provides 15 minutes of thermal inertia during cooling system failures.Special-grade Aluminum with 98% purity ensures consistent thermal performance over the product lifecycle. The material selection complies with ATEX directives for explosive atmospheres.Black Anodized surface treatment enhances corrosion resistance while providing ESD protection. The matte finish reduces glare in machine vision inspection systems.
