evaluation. Provided items include: PC board, cage jacks,

bypass capacitors, thermal washers, terminal strip, spacer

grommets, and heat sink (HS18). The amplier is sold sepa-

rately. Common hardware such as screws and nuts are not

provided.

NOTES:

1. Base material is aluminum, 0.002” thick. Do not allow the

washer to touch pins of the amplier.

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 ow lling 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 TW05 consists of a package of 10 washers.

7. Thermal resistance is 0.05°C/W.
