* Thermal resistance values are measured in free air without airflow obstructions. Thermal resistance is measured from the bottom middle of the heat sink to ambient air, with a heat source at least 4.1cm2. Actual thermal performance may vary by application and final product design should be tested to assure proper thermal performance.
