The **ATS-05B-191-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heatsink**. This part is designed to cool electronic components like CPUs, GPUs, or FPGAs by dissipating heat into the surrounding air. --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of the part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Base Dimensions** | 45mm x 45mm | | **Height** | 30mm | | **Thermal Resistance** | 2.90°C/W @ 100 LFM | | **Attachment Method** | Push-Pin (Plastic) | | **Thermal Interface Material (TIM)** | T766 (High Performance) | --- ### 2. Design and Component Breakdown #### A. The Fin Geometry This part uses a **Straight Fin** design. - **Efficiency:** Straight fins allow for maximum airflow through the heatsink, which is ideal for systems with high-velocity cooling fans. - **Surface Area:** The 30mm height provides a significant surface area for heat exchange compared to low-profile alternatives. #### B. The Attachment System (Push-Pin) Unlike adhesive-based heatsinks, the `C2-R0` series uses a mechanical **Push-Pin** system: - **Material:** Plastic pins with a high-tension spring. - **Benefit:** Provides consistent pressure on the component, improving thermal conductivity. - **Requirement:** Requires pre-drilled holes in the Printed Circuit Board (PCB). #### C. Thermal Interface Material (TIM) The part comes pre-applied with **T766**: - This is a "Phase Change" or high-performance thermal grease that fills microscopic air gaps between the component and the heatsink base. --- ### 3. Decoding the Part Number The part number can be broken down to understand the specific configuration: | Segment | Meaning | | :--- | :--- | | **ATS** | Manufacturer (Advanced Thermal Solutions) | | **05B** | Series/Body Style | | **191** | Specific Dimension Code (45x45x30mm) | | **C2** | Color/Finish (Blue Anodized) | | **R0** | RoHS Compliant Version | --- ### 4. Implementation Example When integrating this into a PCB design, the mechanical footprint must account for the pinholes. In a CAD environment, the layout would look like this: ```markdown # PCB Layout Considerations 1. Keep-out Zone: 45mm x 45mm (Heatsink Body) 2. Hole Diameter: Typically 3.0mm - 3.2mm for push-pins. 3. Hole Pitch: Specific to the 45mm series mounting pattern. ```
