The **ATS-54290K-C2-R0** is a high-performance heat sink component manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "maxiFLOW™" series, specifically designed for cooling electronic components such as processors, FPGAs, and ASICs where space is limited and thermal performance is critical. --- ### 1. Technical Specifications The following table summarizes the key physical and thermal characteristics of this part: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Dimensions (L x W x H)** | 42.9mm x 42.9mm x 14.5mm | | **Material** | Aluminum (Black Anodized) | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Thermal Resistance** | 2.50°C/W @ 200 LFM | | **Shape** | Square, Sloped Fin Design | --- ### 2. Key Components & Design Features #### A. The Fin Geometry (maxiFLOW™) The "K" in the part number refers to the specific sloped fin design. Unlike traditional straight-fin heat sinks, these fins are tapered. This design increases the surface area while reducing pressure drop, allowing for maximum airflow efficiency in congested electronic assemblies. #### B. The Attachment System (maxiGRIP™) One of the most significant "parts" of this assembly is the mounting mechanism: * **Plastic Frame Clip:** A high-strength plastic frame that surrounds the component. * **Stainless Steel Spring Clip:** A "steady-force" spring that applies consistent pressure across the thermal interface material (TIM) without requiring holes in the PCB. #### C. Thermal Interface Material (TIM) The unit typically comes pre-assembled with a high-performance thermal pad or phase-change material on the base to ensure low contact resistance between the electronic chip and the aluminum base. --- ### 3. Application Use Cases This part is typically used in environments where electronic components generate significant heat but have low vertical clearance (only 14.5mm high). * **Telecommunications:** Network switches and high-speed routers. * **Computing:** Embedded systems and industrial PC cooling. * **Power Electronics:** Cooling for high-efficiency DC-DC converters. ---
