It can also be used for effective thermal connection of many heat sinks that require effective cooling. and used for bases and mounting bolts of transistors, diodes and thyristor rectifiers.
Features & Benefits
Non-flowing
no need for ovens or curing
Heat flow away from circuitry components can increase reliability
PrincipleDow thermally conductive compounds are grease like silicone materials, heavily filled with heat-conductive metal oxides. This combination promotes high thermal conductivity, low bleed and high-temperature stability. The compounds are designed to maintain a positive heat sink seal to improve heat transfer from the electrical device or PCB system assemblies to the heat sink or chassis, thereby increasing the overall efficiency of the device. or PCB system assemblies are continually designed to deliver higher performance.
