Product details
NTE Electronics, Inc's NTE497 represents a quantum leap in Thermal - Heat Sinks technology for LED lighting applications. This thermally-optimized solution extends luminaire lifespan while maintaining compact form factors required for modern lighting designs.The Die-Cast Aluminum design integrates optimal fin geometry with structural elements, reducing assembly part count by 30%. Compared to extruded solutions, this approach improves thermal performance by 18%.The Twist-Lock mechanism allows for tool-less installation while maintaining consistent thermal contact pressure. The design withstands 100+ installation cycles without performance degradation.Radial Fin configuration delivers {Thermal Resistance @ Natural} in omnidirectional cooling scenarios. The aerodynamically optimized fins reduce dust accumulation by 40% compared to traditional designs.The 0.500" (12.70mm) dimension accommodates standard LED module sizes while providing sufficient thermal mass. The design prevents thermal shadowing in multi-source luminaires.With 1.380" (35.05mm) coverage, the solution provides uniform cooling for linear LED arrays. Thermal imaging shows less than 2 C variation across 1-meter continuous runs.Precision 2.000" (50.80mm) creates optimal natural convection currents while maintaining IP66 ingress protection. Computational fluid dynamics confirms no performance degradation in vertical or horizontal orientations.The 9.44°C/W specification enables fan-less operation in commercial lighting applications. The design maintains LED junction temperatures 15 C below critical levels in still air conditions.ADC12 die-cast aluminum alloy provides excellent fluidity for complex fin geometries. The material meets UL 746B requirements for long-term thermal aging.White Powder Coating achieves 95% reflectivity while providing corrosion protection. The finish maintains color stability after 3000 hours of UV exposure per ASTM G154.
