Heatsink Compound

This is a 5g syringe of white heatsink compound (aka thermal grease, thermal paste, thermal goo). Use this whenever you're connecting a component to a heatsink, it'll really help to dissipate even more potentially damaging heat.

This compound is composed of 50% silicone, 20% carbon, and 30% metal oxide. It has a thermal conductivity of 1.172 W/(mK), which should be plenty for voltage regulators, MOSFETs, motor drivers, audio amplifiers, etc.

  • Color: White
  • Thermal Conductivity: 1.172 W/(mK)
  • Thermal Impedance: 0.195 -in2/W
  • Specific Gravity: 2.3 @25°C
  • Evaporation: 0.001% - 24 hrs @150°C
  • Bleed: 0.05% - 24 hrs @150°C
  • Moment Beared Temperature: -50-240°C
  • Operation Temperature: -30-180°C
