Main features
- 1.50 mm Medium-Gap of Tflex 600 Series
- 3.0 W/(m K) Thermal Interface
- Easy Assembly and Placement with Naturally Tacky
Product Description
Tflex™ 660 is the 1.50 mm-thick configuration of the Tflex™ 600 Series, an exceptionally soft and highly compliant silicone thermal gap filler designed to bridge interfaces between heat-generating components and adjacent cooling surfaces. The blue-violet pad uses a boron nitride-filled silicone construction to provide typical thermal conductivity of 3.0 W/m·K. Its naturally tacky surfaces support placement during assembly without requiring an additional adhesive coating, making it suitable for applications requiring a medium-thickness thermal interface.
Key features
- 1.50 mm nominal thickness: Specific Tflex™ 600 Series configuration for medium-gap thermal interface applications.
- Highly compliant construction: Soft silicone gap filler conforms to uneven component and heat sink surfaces.
- 3.0 W/m·K thermal conductivity: Boron nitride-filled silicone supports efficient heat transfer across the thermal interface.
- Naturally tacky surfaces: Helps retain pad position during assembly without requiring an additional adhesive coating.
Applications / Suitable for
- Automotive electronics, ADAS, infotainment, and ECU assemblies
- Networking and telecommunications equipment
- Industrial control and power electronics
- Consumer electronics and embedded computing systems
