The **ATS-51270R-C1-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** from the *maxiFLOW™* series manufactured by Advanced Thermal Solutions (ATS). --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of this specific part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Material** | Aluminum (Anodized Blue) | | **Dimensions (L x W x H)** | 27.00mm x 27.00mm x 19.50mm | | **Thermal Resistance** | 3.30°C/W @ 200 LFM | | **Base Shape** | Square | --- ### 2. Key Electronic & Mechanical Components #### A. The Fin Design (maxiFLOW™) Unlike standard extruded heat sinks, this part uses a **tapered fin design**. In electronics, this is critical because: * It maximizes surface area for heat dissipation. * It reduces pressure drop, allowing air to flow more easily through the fins, which is vital for densely packed PCB environments. #### B. The Attachment System (maxiGRIP™) The "R0" designation often refers to the specific attachment kit. This part uses a **four-finger plastic frame clip** and a **stainless steel spring clip**. * **No Holes Required:** It attaches directly to the electronic component (e.g., a BGA chip) without requiring holes in the PCB. * **Thermal Interface Material (TIM):** It typically comes pre-applied with a high-performance thermal pad or phase-change material to ensure low thermal resistance between the silicon die and the aluminum base. #### C. Typical Applications This part is designed to cool high-heat-generating integrated circuits, such as: 1. **FPGAs** (Field Programmable Gate Arrays) 2. **ASICs** (Application Specific Integrated Circuits) 3. **Processors/CPUs** in embedded systems 4. **Network Switches** and Routers --- ### 3. Thermal Performance vs. Airflow Thermal management in electronics is dependent on airflow (Measured in Linear Feet per Minute - LFM): | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 (1.0 m/s) | 3.3 | | 300 (1.5 m/s) | 2.5 | | 400 (2.0 m/s) | 2.1 | | 500 (2.5 m/s) | 1.9 |
