Technical Specifications Below are the primary physical and thermal characteristics of this component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 50mm x 50mm x 30mm | | **Attachment Type** | Push-Pin (Brass) | | **Thermal Interface Material (TIM)** | T766 (High Performance) | | **Fin Style** | Straight (Square) | | **Mounting Hole Pattern** | 43mm x 43mm | --- ### 2. Electronic Application & Performance This part is specifically engineered to manage heat dissipation in constrained spaces. Its effectiveness is measured by **Thermal Resistance**, which determines how many degrees Celsius the temperature rises per Watt of power dissipated. #### Thermal Performance Chart | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100 (0.5 m/s)** | 3.91 | | **300 (1.5 m/s)** | 2.13 | | **500 (2.5 m/s)** | 1.73 | | **700 (3.5 m/s)** | 1.51 | ### 3. Key Electronic Features * **Push-Pin Attachment:** Features a flexible, brass-weighted push-pin mechanism. This provides a secure, consistent mounting pressure onto the electronic chip, ensuring optimal contact with the Thermal Interface Material (TIM). * **T766 Thermal Interface:** The "C2" in the part number indicates it comes pre-applied with T766 phase-change material. This fills microscopic air gaps between the component and the heat sink to maximize heat transfer. * **Omnidirectional Airflow:** While featuring straight fins, the layout is optimized for high-density boards where airflow may come from multiple directions. --- ### 4.
