Main features
- 0.040-Inch Preformed Gap Control
- 2 W/(m K) Interface Heat Transfer
- High-Resistivity Electrical Insulation
Product Description
Tflex B240 is the 0.040 in (1000 um) thickness grade in the ceramic-filled silicone Tflex B200 thermal gap-filler family. The compliant, low-modulus pad combines typical 2.0 W/(m K) thermal conductivity with natural tack on both sides for placement during assembly. Typical Shore 00 hardness is 42, and typical volume resistivity is 2 x 10^13 ohm cm. Standard, center-fiberglass MFG, and one-side FG configurations extend the family's handling options, while a -40 to 150 deg C temperature range supports electronic thermal-interface use.
Key features
- 1000-um thickness: 0.040 in (1000 um) preformed sheet.
- Thermal conductivity: Typical 2.0 W/(m K) conductivity carries heat across the interface.
- Electrical insulation: Typical volume resistivity is 2 x 10^13 ohm cm.
Applications
Applications include automotive ADAS, automotive infotainment, instrumentation, routers, and wireless infrastructure.
