1. Tcase is defined as the maximum case temperature without any thermal enhancement to the package.
The thermal parameters listed in
assembled on a 4-layer 30 x 56 mm mini PCIe board connected to a system board in a
natural convection environment. The maximum case temperature is based on the
maximum junction temperature and defined by the relationship, Tcase-max = Tjmax -
(JT x Power) where JT is the junction-to-package top thermal characterization
parameter. If the case temperature exceeds the specified Tcase max, thermal
enhancements such as heat sinks or forced air are required. JA is the package junction-
to-air thermal resistance.
Thermal models are available upon request (Flotherm 2-Resistor, Delphi or Detailed
format).
Thermal Specifications
To ensure proper operation and reliability of the 82574, the thermal solution must
maintain a case temperature at or below the values specified in
or component-level thermal enhancements are required to dissipate the generated heat
if the case temperature exceeds the maximum temperatures listed in
Good system airflow is critical to dissipate the highest possible thermal power. The size
and number of fans, vents, and/or ducts, and, their placement in relation to
components and airflow channels within the system determine airflow. Acoustic noise
constraints might limit the size and types of fans, vents and ducts that can be used in a
particular design.
To develop a reliable, cost-effective thermal solution, all of the system variables must
be considered. Use system-level thermal characteristics and simulations to account for
individual component thermal requirements.
