| Surface Temperature Versus Power Load (on Chassis) & Derating |
 |
 |
Derating is required to reduce chassis outing area and for high ambient temperatures.
Curves: A=5 & 10 watt units, unmounted.B=25 watt units, unmounted.C=50, 100 & 250 watt units, unmounted.
|
 |
REDUCED HEAT SINK DERATING:
Derating is also required when recommended heat sink
area is reduced.
A = AHL-5 and AHL-10 size resistor.
B = AHL-25 size resistor
C = AHL-50, AHL-100 and AHL-250 size resistor |
