Product details
NTE Electronics, Inc's NTE494 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.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.The 0.750" (19.05mm) dimension aligns with standard DIN rail spacing, simplifying integration into industrial control systems. The extruded profile maintains dimensional stability within 0.1mm tolerance.With 0.500" (12.70mm) coverage, the heatsink protects sensitive components from thermal crosstalk. Infrared analysis shows less than 2 C variation across parallel-mounted devices.The 0.500" (12.70mm) is calibrated for optimal performance in both horizontal and vertical orientations. Finite element analysis confirms no performance degradation at 45 mounting angles.The 27.30°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.
