Phase Change Material HP-40 4.0W
Features
- High thermal conductivity
- Good electrical insulation
- Excellent surface wetting
- Excellent reliability
Phase Change Material (PCM) is a solid sheet at room temperature, making it easy to cut and assemble. Once the component heats up to the phase change temperature, the material softens and flows to fully fill the microscopic gaps between the heat source and the heatsink, greatly reducing interface thermal resistance for fast heat dissipation.
Selection Guide
Mid-range model: 4.0 W/mK and thermal resistance ≤0.19 °C·in²/W, balancing thermal performance and cost. Suited to notebook and desktop CPUs, networking equipment and power supplies.
Applications
5G, electric vehicles, power supplies, servers, notebooks, desktops, CPUs, ICs, wireless hubs, LEDs, motherboards, heatsinks, LCD TVs, telecom equipment, AIoT and more.
