The **ATS-55450R-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It belongs to the **maxiFLOW™** series, which is specifically designed to provide high thermal performance in environments with constrained airflow. --- ## 1. Technical Specifications The following table summarizes the key physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Series** | maxiFLOW™ | | **Material** | Aluminum (Anodized Blue) | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Dimensions (L x W)** | 45.00mm x 45.00mm | | **Height** | 19.50mm | | **Thermal Resistance** | 1.40°C/W (at 200 LFM) | | **Flow Pattern** | Directional (High fin density) | --- ## 2. Key Components & Technologies ### A. maxiFLOW™ Fin Design Unlike standard square-fin heat sinks, the maxiFLOW™ design features a flared fin structure. This increases the surface area and creates a pressure differential that pulls more air through the fin field, significantly reducing the junction temperature of the electronic component it cools. ### B. maxiGRIP™ Attachment System One of the most critical "parts" of this assembly is the attachment mechanism: * **Plastic Frame Clip:** This clips directly around the component (e.g., a BGA or FPGA). * **Steady Spring Force:** It uses a high-performance gold-colored "SteadyDrive" spring clip. * **No Holes Required:** It eliminates the need to drill holes into the PCB, which preserves signal integrity and saves board space. ### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates that the heat sink comes pre-assembled with a high-performance **Thermal Interface Material**. This is a phase-change or pad-based material applied to the base to ensure there are no air gaps between the heat sink and the semiconductor die. --- ## 3. Applications This part is commonly used for cooling high-heat-generating electronic components such as: * **FPGAs (Field Programmable Gate Arrays)** * **ASICs (Application Specific Integrated Circuits)** * **CPUs/Processors** in embedded systems. * **Network Switches** and high-speed routers.
