The **ATS-20D-161-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 Below are the primary physical and thermal characteristics of the part: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 45mm x 45mm x 20mm | | **Thermal Resistance** | 4.74°C/W (at 200 LFM) | | **Attachment Method** | pushPIN™ (Brass Springs) | | **Fin Style** | Straight Fin | | **Flow** | Cross-cut (Multiple directions) | --- ### 2. Key Features * **pushPIN™ Attachment:** It features a specialized attachment system that provides a secure, consistent pressure on the electronic component, ensuring optimal thermal interface material (TIM) performance. * **Optimized Fin Design:** The "Straight Fin" design is optimized for high-performance air-cooling environments, allowing air to pass through easily while maximizing surface area. * **Blue Anodized Finish:** Beyond aesthetics, the anodization protects the aluminum from corrosion and slightly improves thermal emissivity. * **Pre-assembled:** It typically comes with a pre-applied Thermal Interface Material (TIM) on the base to simplify the assembly process. --- ### 3. Electronic Application This part is commonly used in industrial and consumer electronics where airflow is present (active cooling). * **Target Components:** High-speed processors, FPGA chips, and Power MOSFETs. * **Mechanical Footprint:** The 45mm square base is a standard size for many mid-to-large scale Integrated Circuits (ICs). * **Thermal Calculation Example:** If your component generates **10 Watts** of heat and the airflow is 200 LFM: `Temperature Rise = 10W * 4.74°C/W = 47.4°C` above ambient temperature. --- ### 4.
