Thermal Specifications
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:
Ψ
CA
= 0.29 + (45.2 - T
AMBIENT
) x 0.0353
3. This column can be expressed as a function of T
AMBIENT
by the following equation:
Ψ
CA
= 0.289 + (45.2 - T
AMBIENT
) x 0.0222
