Honeywell PTM7950 Phase Change Thermal Pad GPU CPU Heatsink Phase Change Cooling Conductive Silicone Pad Cooler Mat Main Features 0.04 Thermal Impedance 8.5 Thermal Conductivity 0.25 Thickness Product PTM7950 is a super highly thermally conductive Phase Change Material (PCM) in both pad and paste formats. It is designed to minimize thermal resistance at interfaces, maintain excellent performance through reliability testing, and provide scalable application at a competitive cost. PTM7950, based on a novel polymer PCM system, exhibits excellent interface wetability during typical operating temperature ranges, resulting in extremely low surface contact resistance. Since PTM7950 comes only in 0.25mm (thicker versions are under development) you need to be sure that this thickness is compatible and suitable for the flatness of your package. PTM7950 is a proprietary material that provides superior reliability (pass 150C baking 1000 hours, T/C-B 1000 cycles) and maintains low thermal impedance ( Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Dadangjia
