HEATSINKS
The following heatsinks are mechanically compatible with
this amplifier. Thermal ratings are for optimum mounting in
free air.
HS18 1°C/W
CAGE JACKS
HS06
0.96°C/W
MS04
HS11 0.68°C/W
With liquid cooling the HS11 thermal rating can be reduced
to 0.1°C/W.
Part number MS04 consists of a package of 12 cage jacks.
These are mounted directly in a print circuit board. Use a spacer
between the PCB and the heatsink to avoid short circuits.

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 TW05 consists of a package of 10 washers.
7. Thermal resistance is 0.05°C/W.
