Item # T766, THERMFLOW Phase-Change Thermal Interface Pads On Robert McKeown Co., Inc.

THERMFLOW™ materials are thermally enhanced polymers designed to minimize the thermal resistance between power dissipating electronic components and their associated heat sinks. This low thermal resistance path maximizes heat sink performance and improves the reliability of microprocessors, memory modules, DC/DC converters and power modules.

The key feature of THERMFLOW materials is their phase-change characteristic. At room temperature, THERMFLOW materials are solid and easy to handle. Thismore
