The **ATS-54270W-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is specifically designed for cooling electronic components such as CPUs, GPUs, and other high-power ICs (Integrated Circuits). --- ### 1. Technical Specifications The following table summarizes the physical and thermal characteristics of the part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Heat Sink Type** | Fin Geometry (High Aspect Ratio) | | **Attachment Method** | maxiGRIP™ (Frame clip) | | **Length x Width** | 42.70 mm x 42.70 mm | | **Height** | 24.50 mm | | **Material** | Aluminum (Black Anodized) | | **Thermal Resistance** | ~1.40 °C/W (at 200 LFM) | --- ### 2. Key Electronic & Design Features #### A. maxiFLOW™ Fin Geometry The "W" in the part number refers to the **maxiFLOW** design. Unlike standard straight-fin heat sinks, this design features a spread-fin pattern that: * Reduces pressure drop. * Increases the surface area for heat dissipation. * Optimizes airflow from any direction, making it ideal for high-density PCBs. #### B. maxiGRIP™ Attachment One of the most critical aspects of this part for electronic assembly is the **maxiGRIP™** system: * **Mechanical Clip:** It uses a plastic frame clip and a stainless steel "X-clip." * **No Holes Required:** It attaches directly to the component without requiring holes in the PCB, saving valuable board "real estate." * **Steady Pressure:** It provides consistent pressure to ensure the Thermal Interface Material (TIM) performs efficiently. #### C. Material and Finish * **Aluminum 6063:** Chosen for its high thermal conductivity and lightweight properties. * **Black Anodized Finish:** This is not just for aesthetics; the black anodization increases **thermal emissivity**, allowing the part to radiate heat more effectively into the surrounding environment. --- ### 3. Application Use Cases This specific heat sink is typically found in the following electronic environments: 1. **Telecommunications:** Cooling high-speed networking chips and routers. 2. **Embedded Systems:** Industrial PCs where space is limited but heat output is high. 3. **Power Electronics:** Cooling MOSFET arrays or voltage regulators. ---
