Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL-6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W)** | 45.00 mm x 45.00 mm | | **Height** | 25.00 mm | | **Pitch/Pattern** | Square | | **Thermal Resistance** | 5.10°C/W (at 100 LFM) | --- ### 2. Physical Design and Construction #### Fin Profile The unit features a **straight fin** design. Straight fins allow for optimal airflow when used with a directional fan, minimizing the pressure drop across the heat sink while maximizing surface area for heat dissipation. #### Attachment Mechanism: pushPIN™ This part utilizes a specific mounting system: * **Compression Springs:** Provide a precise amount of pressure (preload) on the component to ensure a consistent thermal interface. * **Plastic/Brass Push Pins:** Designed to snap into pre-drilled holes (usually 3.0mm) on a PCB, ensuring secure attachment without the need for additional screws. #### Thermal Interface Material (TIM) The "C3" in the part number indicates that this specific model usually comes with **T766** high-performance thermal grease or a similar phase-change material pre-applied to the base to improve conductivity between the chip and the aluminum. --- ### 3. Thermal Performance Metrics The efficiency of this heat sink varies based on the airflow velocity (measured in Linear Feet per Minute - LFM): | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 5.10 | | 200 (1.0 m/s) | 2.50 | | 300 (1.5 m/s) | 1.80 | | 500 (2.5 m/s) | 1.30 | --- ### 4. Implementation Details ```cpp // Thermal Design Power (TDP) Calculation Example // If your component generates 15W and the max ambient temp is 40°C: float power_watts = 15.0; float thermal_resistance = 1.80; // at 300 LFM float ambient_temp = 40.0; float junction_temp = ambient_temp + (power_watts * thermal_resistance); // Result: 67.0°C (Well within safe operating limits for most ICs) ``` ---
