INTRAPHASE 50 PHASE CHANGE MATERIAL (ALUMINUM FOIL)
Intraphase 50 Phase Change Thermal Interface Material
IntraPhase 50 is a graphite filled phase-change thermal interface material offering high performance heat transfer packaged with a clean drop-in-place assembly solution. IntraPhase 50 offers low thermal impedance within a range of pressure requirements which makes it an ideal solution for a range of power devices including power modules, transistors, diodes and microprocessors.
IntraPhase 50 not only achieves efficient thermal transfer through its unique filled coating formulation, however, by phase-changing during normal device operating temperatures while maintaining a uniform bond line thickness thus driving out the air and adjusting for any surface imperfections or flatness concerns that may exist across a small or large interface footprint.
