Technical Specifications Below are the primary physical and thermal characteristics of this part: | Characteristic | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance** | 15.85°C/W (at 200 LFM) | | **Attachment Method** | Push-Pin (Plastic) | | **Spring Type** | Compression Spring | | **Heat Sink Type** | Top Mount (Cross-Cut) | | **Thermal Interface (TIM)** | T766 (Pre-applied) | --- ### 2. Physical Dimensions Precision measurements are critical for PCB layout and clearance planning: | Dimension | Value (mm) | | :--- | :--- | | **Length/Width** | 40.00 mm x 40.00 mm | | **Height** | 10.00 mm | | **Pin Pitch** | 33.00 mm | --- ### 3. Key Electronic/Mechanical Features * **Cross-Cut Fin Pattern:** The fins are cut in both directions. This design allows for multidirectional airflow, making it ideal for systems where the air direction might change or is turbulent. * **Push-Pin Attachment:** The use of plastic push-pins and a brass/steel spring ensures consistent pressure on the electronic component, which optimizes heat transfer while preventing damage to the PCB. * **Pre-applied TIM:** It comes with **T766 thermal interface material**, which eliminates the need for manual application of thermal paste during assembly, ensuring a reliable bond between the component and the heat sink. * **Blue Anodized Coating:** The surface treatment is not just aesthetic; it increases the surface emissivity, which slightly improves radiative heat transfer and protects the aluminum from corrosion. --- ### 4. Common Applications * **Integrated Circuits (ICs):** Cooling FPGAs, ASICs, and high-speed processors. * **Power Electronics:** Dissipating heat from MOSFETs and voltage regulators. * **Telecommunications:** Used in routers and switches where airflow is provided by system fans.
