The **ATS-18A-47-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 high-power semiconductors. --- ### 1. Key Technical Specifications Below are the physical and thermal characteristics of the part: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Dimensions** | 25mm x 25mm x 30mm | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Attachment Material** | Brass (Nickel plated) | | **Thermal Resistance** | 3.69° C/W @ 100 LFM | | **Fins** | Cross-Cut (Pin Fin) | --- ### 2. Physical Design & Cooling Efficiency The part utilizes a specialized design to maximize airflow and thermal dissipation in tight spaces. * **Fin Style (Cross-Cut):** Unlike straight-fin heat sinks, the "Cross-Cut" or "Pin Fin" pattern allows for multi-directional airflow. This is critical in systems where the direction of the cooling fan's exhaust might vary. * **Vertical Height (30mm):** This is a relatively tall heat sink for its base size (25x25mm), providing a larger surface area for heat exchange without occupying a large footprint on the PCB. --- ### 3. Attachment Mechanism: pushPIN™ The "R0" designation typically refers to the mounting hardware included. This model uses the **ATS pushPIN™** system: * **Security:** It provides high pressure to ensure a tight seal between the component and the heat sink. * **Installation:** Uses pre-drilled holes in the PCB. It includes a compression spring to prevent over-tightening while maintaining constant contact. * **TIM (Thermal Interface Material):** These units usually come with a pre-applied high-performance thermal phase-change material or grease for immediate installation. --- ### 4. Part Number Breakdown Understanding the nomenclature helps in identifying variants: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **18A:** Series/Size family. * **47:** Specific design/thermal profile. * **C2:** Material/Color (Aluminum, Blue Anodized). * **R0:** Packaging or hardware revision (Standard mounting kit). ---
