The **ATS-05D-209-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) Heat Sink** designed for cooling electronic integrated circuits (ICs) and surface-mount components. --- ## 1. Technical Specifications The part number follows a specific nomenclature used by ATS for their "push-pin" series. | Parameter | Specification | | :--- | :--- | | **Product Type** | Heat Sink | | **Attachment Method** | Push-Pin (Plastic or Brass) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance** | ~6.27°C/W (at 200 LFM) | | **Dimensions (L x W)** | 70mm x 70mm | | **Height (Fin Height)** | 10mm | | **Fin Style** | XC-Cut (Cross-cut) | --- ## 2. Key Component Features ### A. Push-Pin Attachment Instead of using messy thermal adhesives or tapes, this part uses a mechanical **Push-Pin** system. * **Spring-loaded:** Ensures consistent pressure (clamping force) between the heat sink and the chip. * **Stability:** Provides a more secure mount in high-vibration environments compared to adhesive tapes. ### B. XC-Cut Fin Design The "XC-Cut" refers to the cross-cut fin geometry. * **Multi-directional Airflow:** Unlike straight-fin heat sinks that require air to move in one specific direction, cross-cut fins allow air to enter from multiple angles. * **Surface Area:** This design maximizes the surface area to volume ratio, increasing the efficiency of heat dissipation. ### C. Blue Anodized Finish The blue coating is not just for aesthetics: * **Corrosion Resistance:** Protects the aluminum from oxidation. * **Emissivity:** Anodized surfaces generally have higher emissivity than bare aluminum, slightly improving radiation heat transfer. --- ## 3. Applications This part is typically found in the following electronic systems: * **Networking Gear:** Switches, routers, and high-speed modems. * **Computing:** High-performance CPUs, GPUs, or FPGAs. * **Power Electronics:** Cooling MOSFET arrays or power modules where vertical space is limited (10mm height). --- ## 4. Part Number Breakdown The suffix `C2` specifically refers to the **Thermal Interface Material (TIM)** and the hardware: * **C2:** Indicates that the heat sink usually comes with a pre-applied **T766 phase change material** or high-performance thermal pad, and features a specific spring/pin combination. * **R0:** Refers to the revision code or RoHS compliance (Lead-free).
