## ATS-53425D-C1-R0: High-Performance Heat Sink Overview The **ATS-53425D-C1-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "maxiFLOW™" series, specifically designed for high-density cooling requirements in electronic components like CPUs, GPUs, and ASICs. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Base Series** | maxiFLOW™ | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Material** | Aluminum (Body) | | **Finish** | Blue Anodized | | **Thermal Resistance** | 2.50°C/W @ 200 LFM | | **Dimensions (L x W)** | 42.50mm x 42.50mm | | **Height** | 9.50mm | --- ### 2. Key Component Features #### A. maxiFLOW™ Fin Design The fin geometry is tapered and flared. Unlike standard square fins, this design increases the surface area for heat dissipation while maintaining a low pressure drop. This allows more air to flow through the heat sink even in environments with high component density. #### B. maxiGRIP™ Attachment The part uses a specialized "Frame Clip" attachment system: * **Plastic Frame:** A plastic frame is clipped around the component. * **Stainless Steel Spring Clip:** A "steady-force" spring clip applies uniform pressure across the component surface, ensuring optimal thermal interface material (TIM) performance. * **No Holes Required:** It eliminates the need to drill holes into the PCB, saving board space and reducing manufacturing complexity. #### C. Thermal Interface Material (TIM) The "R0" suffix usually indicates that the heat sink comes pre-assembled with a high-performance thermal pad (typically Chomerics T766 or equivalent), ensuring immediate readiness for installation. --- ### 3. Application Use Cases 1. **Telecommunications:** Cooling of high-speed networking chips and routers. 2. **Data Centers:** Low-profile cooling for server-mounted components where vertical space is limited (9.5mm height). 3. **Embedded Systems:** Industrial PCs and automated control systems that require vibration-resistant mounting. --- ### 4. Selection Criteria When integrating this part into a circuit design, engineers focus on: * **Thermal Budget:** Ensuring the 2.50°C/W resistance (at target airflow) keeps the junction temperature below the chip's limit. * **Clearance:** Ensuring the 42.5mm footprint does not interfere with nearby capacitors or inductors. * **Airflow Direction:** The flared fins are designed to take advantage of directional airflow.
