The **ATS-21D-48-C2-R0** is a high-performance thermal management component specifically designed for cooling electronic integrated circuits (ICs). It belongs to the **Advanced Thermal Solutions (ATS)** "maxiFLOW" family. ### 1. Component Overview This part is a **Heat Sink** assembly. Its primary purpose is to dissipate heat from surface-mount components (like CPUs, GPUs, or FPGAs) into the surrounding air to prevent thermal throttling or hardware failure. --- ### 2. Technical Specifications | Feature | Details | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. | | **Series** | maxiFLOW™ | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | maxiGRIP™ (Steady pressure clip) | | **Dimensions (L x W x H)** | 40mm x 40mm x 23mm | | **Thermal Resistance** | 2.82°C/W @ 200 LFM | | **Airflow Direction** | Directional (High-performance fin geometry) | --- ### 3. Key Electronic/Mechanical Features #### A. The maxiFLOW™ Fin Design Unlike standard cross-cut heat sinks, this part uses a **tapered fin design**. This increases the surface area while reducing the pressure drop, allowing air to flow more efficiently through the fins. This is critical in densely packed electronic enclosures. #### B. maxiGRIP™ Attachment System One of the most important aspects of this part is how it interacts with the PCB: * **Plastic Frame Clip:** It uses a high-tension plastic frame that surrounds the component. * **Stainless Steel Spring Clip:** A "C" shaped spring clip applies constant, uniform pressure across the thermal interface material (TIM). * **No Holes Required:** It attaches directly to the component package, meaning you do not need to drill holes in the PCB. #### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates that the part comes pre-applied with a high-performance thermal phase-change material or tape, ensuring low thermal resistance between the silicon die and the aluminum base. --- ### 4. Typical Applications * **Telecommunications:** High-speed routers and switches. * **Computing:** Embedded systems and server blades. * **Power Supplies:** Cooling MOSFETs or power regulators.
