Features: PTM7950 thin thermal pad delivers exceptionally thermal conductivity (8.5W/m.K) and low thermal resistance (less than 0.04°Ccm²/W), optimized for high performances electronics cooling solution in computers and server hardware. Featuring a precise thin and proprietary r, this thermal pad ensures reliabled heat transfer across uneven surfaces while passing rigorous 150°C/1000hr baking and thermal cycling tests. Ideal for engineers and PC enthusiasts upgrading CPU/GPU cooling systems or designing small thermal management solution for powerful integrated circuits. Perfectly adapts to heat sinks, processors, and power module in gaming PC, data center servers, and industrial equipment requiring stable long time thermal performances. This cost effective thermal pad alternative combines scalable application with industrial durability, for electronics thermal design. Specifications: Thickness of the thermal pad usually less than 1.5mil (0.038mm) for optimaled performances Reliability after thermal resistance (ASTM E1461) Production line end 0.04˚C-cm2/W Baking 150˚C, 1000 hours 0.04˚C-cm2/W Double 85, 1000 hours 0.04˚C-cm2/W Temperature cycle B (-55˚C to +125˚C, 1000 cycles) 0.045˚C-cm2/W Size：about 20X20mm/0.78x0.78in 40X40mm/1.57x1.57in 50X31mm/1.97x1.22in 40X80mm/1.57x3.15in 80X80mm/3.15x3.15in 80X160mm/3.15x6.3in 400X160mm/15.75x6.3in Package Includes: 1PC ptm7950 Thermal pad note: Please allow 1-2cm errors due to manual measurement.
