Technical Specifications | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Dimensions (L x W x H)** | 25mm x 25mm x 15mm | | **Fin Style** | Straight Fin | | **Thermal Resistance (Unducted)** | 12.30 °C/W @ 100 LFM | | **Thermal Resistance (Ducted)** | 3.91 °C/W @ 100 LFM | | **Thermal Interface Material (TIM)** | T412 (High performance) | --- ### 2. Key Components & Design Features #### A. The Heat Sink Body The part is made of **Aluminum 6063**, chosen for its excellent thermal conductivity and lightweight properties. The "Straight Fin" design provides a high surface area to volume ratio, which is ideal for environments with steady airflow. #### B. The pushPIN™ Attachment System Unlike adhesive-based heat sinks, this model uses a mechanical mounting system: * **Plastic/Brass Pins:** Inserted into pre-drilled holes on the PCB. * **Compression Springs:** Ensure constant, high pressure between the heat sink and the component, maximizing heat transfer. #### C. Thermal Interface Material (TIM) The base comes pre-applied with **T412**, a phase-change material or high-quality thermal grease. This fills microscopic air gaps between the component and the heat sink to reduce thermal resistance. --- ### 3.
