The **ATS-05F-209-C2-R0** is a high-performance electronic 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 failure. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 70mm x 70mm x 10mm | | **Thermal Resistance** | 6.27°C/W (at 100 LFM) | | **Attachment Method** | Push-Pin (with Compression Springs) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Design Features #### A. Fin Profile: XC-CUT This model features **XC-CUT** fin geometry. These are straight-fin heat sinks with cross-cuts. This design allows for: * **Omnidirectional Airflow:** It can accept airflow from multiple directions, unlike standard straight fins which require air to flow along the channel. * **Increased Surface Area:** The cross-cuts increase the total surface area for heat radiation. #### B. Attachment System: Push-Pins The "05F" and "R0" designations often correlate to the mounting hardware. * **Push-pins:** Provide a secure, vibration-resistant mechanical connection to the PCB. * **Compression Springs:** These ensure consistent pressure between the heat sink and the electronic component, which is critical for efficient heat transfer. #### C. Thermal Interface Material (TIM) The unit comes with **T766** pre-applied to the base. This is a phase-change or high-conductivity material that fills microscopic air gaps between the chip surface and the heat sink base. --- ### 3. Applications This specific size (70mm) and low profile (10mm) make it suitable for: 1. **Telecommunications:** High-speed routers and switches. 2. **Industrial Computing:** Embedded systems where vertical space is limited. 3. **Power Supplies:** Cooling MOSFETs or power conversion modules. --- ### 4. Thermal Performance Comparison *Thermal resistance indicates how effectively the part moves heat away (lower is better).* | Velocity (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 100 | 0.5 | 6.27 | | 300 | 1.5 | 3.46 | | 500 | 2.5 | 2.50 |
