50 Thermal/Mechanical Specifications and Design Guidelines
Notes:
1. The ambient temperature is measured at the inlet to the processor thermal solution.
2. This column can be expressed as a function of T
AMBIENT
by the following equation:
Y
CA
= 0.48 + (48.2 - T
AMBIENT
) x 0.0377
3. This colu4n can be expressed as a function of T
AMBIENT
by the following equation:
Y
CA
= 0.48 + (48.2 - T
AMBIENT
) x 0.0222
