T405 thermal tape consists of a high bond strength, pressure-sensitive acrylic adhesive, loaded with aluminum oxide and coated onto a 0.050 mm (0.002 inch) aluminum foil carrier. The aluminum foil provides added thermal conductivity for applications where electrical isolation is not required.
T412 thermal tape consists of a high bond strength, pressure-sensitive acrylic adhesive, loaded with titanium diboride and applied to an expanded aluminum carrier. The combination of filler, expanded metal and embossed surface enhances both tape conformability and thermal performance.

- Part Number RT5635B00000
- Choose a tape option T405 (05), T410 (10), T411 (11)
or T412 (12)
- Then add the ordering code (05,10,11,12) to
your part number (by replacing the last two digits.)
For Example: To order tape option T410 (10) with the part number RT5635B00000 the completed part number to order would be RT5635B00010. |

T410 tape consists of a high bond strength, pressure sensitive acrylic adhesive loaded with aluminum oxide and coated onto a 0.05 mm (0.002 inch) aluminum foil carrier. The other side of the foil carrier has a Silicon pressure sensitive adhesive which provides excellent adhesion to Silicon-contaminated plastics and other low energy surfaces.
T411 tape consists of a high bond strength pressure-sensitive adhesive with an expanded aluminum mesh carrier layer. The mesh carrier allows the tape to conform to curved surfaces of plastic molded IC packages, providing a high adhesive strength attachment for heat sinks. The high performance Silicon PSA allows adhesion to Silicon-contaminated plastics and other low energy surfaces.
