The part number **ATS-18D-81-C2-R0** refers to a high-performance **Heatsink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "superGRIP" series, designed for cooling electronic components such as CPUs, GPUs, and FPGAs. ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | superGRIP™ | | **Material** | Aluminum (Heatsink), Copper (Attachment mechanism) | | **Finish** | Blue Anodized | | **Dimensions** | 30.00mm x 30.00mm | | **Height** | 20.00mm | | **Thermal Resistance** | 14.03°C/W (at 200 LFM) | | **Attachment Method** | superGRIP (Clip-on) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Component Features #### A. Fin Design The "81" in the part number indicates a specific **straight-fin** or **cross-cut** configuration. These fins increase the surface area available for heat dissipation. Because it is aluminum, it offers a balance between lightweight design and efficient thermal conductivity. #### B. superGRIP™ Attachment Unlike traditional heatsinks that require holes in the PCB, this model uses a high-strength plastic frame clip and a gold-plated brass spring clip. * **No PCB holes required:** It attaches directly to the component. * **High Force:** Provides strong contact pressure for the Thermal Interface Material (TIM). #### C. Thermal Performance The efficiency of this part is measured by its resistance to heat flow. Lower values are better for higher workloads: * **@ 200 LFM (Linear Feet per Minute):** 14.03°C/W * **@ 500 LFM:** 8.34°C/W #### D. Blue Anodized Finish The blue coating is not just for aesthetics; it provides a protective layer against corrosion and slightly improves radiant heat transfer compared to raw aluminum. --- ### 3. Part Number Breakdown The nomenclature can be deciphered as follows: * **ATS:** Advanced Thermal Solutions (Manufacturer) * **18D:** Series and Clip type * **81:** Specific Fin Pattern/Geometry * **C2:** Material/Color Code (usually Blue Anodized) * **R0:** Revision/Packaging code --- ### 4. Typical Applications * **Network Switches/Routers:** For cooling high-speed processors. * **Power Supplies:** Managing heat in localized MOSFETs. * **Embedded Systems:** Ideal for space-constrained boards where drilling holes for screws is impossible.
