DERATING
: Power rating is based on the use of a suitable heat sink and thermal
compound to limit case temp. to 200°C. Derate wattage 0.44%/°C above 25°C.
Recommended aluminum chassis area is 64in² x.040” thick for type 605 and 610,
83in² x.040” thick for type 615, 144in² x.060” thick for type 620, and 144in² x .125”
for types 625 through 640. Without a heat sink, derate wattage rating by 60%.
