NOTES:
1. Base material is aluminum, 0.002” thick. Do not allow the
washer to touch pins of the amplifier.
2. For optimum thermal transfer, avoid abrasive handling of
washers which can damage their 0.5mil thick layer of thermal
compound with which each side is coated.
3. The dry thermal compound will flow filling header to heatsink
voids as soon as the material reached 60°C.
4. Do not store unused thermal washers above 40°C.
5. A new washer must be used for each mounting.
6. Part number TW03 consists of a package of 10 washers.
7. Thermal resistance is 0.1°C/W.
