The **ATS-19F-126-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It belongs to the **maxiFLOW™** series, designed to dissipate heat from electronic components like CPUs, GPUs, and power modules. --- ## 1. Technical Specifications Below are the primary technical parameters for this specific part number: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | 5.47°C/W (Unducted Flow @ 200 LFM) | | **Dimensions (L x W x H)** | 54mm x 54mm x 15mm | | **Base Shape** | Square | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ## 2. Key Features and Components ### A. pushPIN™ Attachment Unlike traditional adhesive-based heat sinks, the "R0" suffix indicates the inclusion of the **pushPIN™** mounting system. * **Hardware:** It uses a brass or plastic pin with a stainless steel spring. * **Reliability:** Provides a precise, calculated pressure (C2) to ensure optimal contact with the electronic component. ### B. maxiFLOW™ Fin Design The fin geometry is designed to maximize surface area while minimizing pressure drop. The spread-fin architecture allows for improved air intake and exhaust, which is crucial in high-density PCB environments. ### C. Blue Anodized Finish The aluminum is treated with a blue anodized coating. This is not purely aesthetic; it provides: * Increased corrosion resistance. * Enhanced surface emissivity for better radiation heat transfer. * Electrical insulation of the heat sink surface. ### D. Pre-applied TIM (Thermal Interface Material) The unit comes with **T766** pre-applied to the base. This ensures that the microscopic air gaps between the heat sink and the chip are filled with a thermally conductive material, significantly reducing thermal resistance right out of the box. --- ## 3. Decoding the Part Number The part number follows a specific nomenclature: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **19F:** Series designation (maxiFLOW™). * **126:** Specific size and fin configuration code. * **C2:** Thermal performance/Spring tension category. * **R0:** Revision/Packaging code (Standard pushPIN™ assembly). --- ## 4. Typical Applications This component is generally used in: * **Networking:** Switches and routers where airflow is managed but space is tight. * **Telecommunications:** Base stations and signal processing units. * **Embedded Computing:** Industrial PC processors that require robust physical mounting against vibration.
