The **ATS-18H-129-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push-pin" attachment series designed for cooling electronic components like CPUs, GPUs, and power transistors. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Type** | Push-Pin (Spring-loaded) | | **Dimensions** | 54.00 x 54.00 x 20.00 mm | | **Fin Style** | Square Pin Fin (High Flow) | | **Thermal Resistance** | 2.86°C/W (at 200 LFM) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Breakdown of the Model Number The part number follows a specific nomenclature used by ATS to identify the product's attributes: * **ATS-18H**: Indicates the series and the specific spring/push-pin assembly type. * **129**: Refers to the specific size and fin configuration within that series. * **C2**: Specifies the material and finish (typically Aluminum with a Blue Anodize). * **R0**: Indicates the revision level or packaging standard. --- ### 3. Key Electronic Functions While the part itself is passive, its role in an electronic system is critical for hardware longevity: 1. **Heat Dissipation:** It increases the surface area of a semiconductor package, allowing heat to transfer more efficiently into the surrounding air via convection. 2. **Thermal Protection:** By lowering the junction temperature of a chip, it prevents **thermal throttling** (where a processor slows down to stay cool) and catastrophic failure. 3. **Mechanical Stability:** The "Push-Pin" design provides a consistent downward force, ensuring that the **Thermal Interface Material (TIM)** maintains a perfect bridge between the heat source and the heat sink. 4. **Airflow Optimization:** The square pin-fin pattern is designed to be "omni-directional," meaning it performs well regardless of which direction the cooling fan's air is blowing. --- ### 4. Application Areas * **Networking Hardware:** Routers, switches, and high-speed modems. * **Embedded Systems:** Industrial PCs and automation controllers. * **Power Electronics:** Voltage regulators and high-power MOSFETs that generate significant waste heat.
