The **ATS-03D-40-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) Push-Pin Heat Sink**. It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power transistors. ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | Push-Pin (Plastic) with Spring | | **Thermal Resistance** | 14.56°C/W @ Natural Convection | | **Dimensions (L x W x H)** | 45mm x 45mm x 25mm | | **Fin Style** | Straight Fin | | **Interface Material** | T766 (Pre-applied Thermal Phase Change Material) | --- ### 2. Key Electronic & Mechanical Components The "electronic" functionality of this part is passive, focusing on heat transfer through conduction and convection. #### A. The Heat Sink Body * **Material:** Constructed from high-grade aluminum. Aluminum is chosen for its high thermal conductivity and lightweight properties. * **Fin Geometry:** It features a "straight fin" design. In electronics, the fins increase the surface area exposed to the air, allowing heat to be carried away faster by airflow (forced or natural). #### B. The Push-Pin Mounting System * **Component:** Plastic push-pins and compression springs. * **Function:** This ensures a consistent "clamping force" on the electronic chip. In sensitive electronics, too much pressure can crack a die, while too little creates an air gap that causes overheating. The spring-loaded pins provide a precise, repeatable pressure. #### C. Thermal Interface Material (TIM) * **Component:** T766 Phase Change Material. * **Function:** This is a thin layer applied to the bottom of the heat sink. At room temperature, it is solid, but as the electronic component heats up, it softens to fill microscopic gaps between the chip and the metal, ensuring maximum heat transfer. --- ### 3. Application Use Cases This specific model is typically found in the following electronic environments: 1. **Telecommunications:** High-speed routers and switches. 2. **Embedded Computing:** Industrial PC boards where vibration resistance is needed (the push-pins lock the sink in place). 3. **Power Supplies:** Cooling voltage regulators or MOSFETs. ---
