The **ATS-04D-05-C2-R0** is a high-performance thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors to prevent thermal throttling or hardware failure. --- ### 1. Technical Specifications The following table summarizes the primary physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Dimensions** | 40mm x 40mm x 25mm | | **Material** | Aluminum (AL6063) | | **Fin Style** | Push-Pin (High Efficiency) | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) with Compression Spring | | **Thermal Resistance** | 19.27°C/W (Unducted @ 1.0 m/s) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Design and Engineering Features ### A. Fin Geometry (Cross-Cut) The "D" in the part number often signifies a specific fin pattern. This heat sink uses a **straight-fin or cross-cut design** optimized for both natural convection and forced airflow. The spacing between fins is calculated to minimize pressure drop while maximizing surface area. ### B. Push-Pin Attachment Mechanism Instead of using adhesive tapes which can degrade over time, this part uses a **Push-Pin and Spring** system: * **Reliability:** Provides consistent pressure on the chip for optimal heat transfer. * **Ease of Installation:** Snaps into pre-drilled holes on the PCB (usually 3.0mm holes). * **Durability:** The compression springs are designed to withstand mechanical shock and vibration. ### C. Thermal Interface Material (TIM) The unit comes with **T766** pre-applied to the base. This is a "Phase Change" or high-performance thermal pad that fills microscopic air gaps between the heat sink and the electronic component, significantly reducing thermal contact resistance. --- ### 3. Application Use Cases This specific model is commonly found in industrial and computing environments: * **Embedded Systems:** Cooling for ARM-based processors or FPGAs. * **Networking Gear:** Used on chipsets inside routers, switches, and modems. * **Power Electronics:** Dissipating heat from Motor Drivers or high-power MOSFETs. ---
