The **ATS-61270W-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is specifically designed for cooling high-power electronic components, particularly in the telecommunications and networking sectors. --- ### 1. Component Specifications The following table highlights the physical and thermal characteristics of this specific model: | Attribute | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Heat Sink Type** | maxiFLOW™ High-Performance Heat Sink | | **Dimensions (L x W x H)** | 27mm x 27mm x 24.5mm | | **Material** | Anodized Aluminum (Blue) | | **Attachment Method** | superGRIP™ Clip (typically) | | **Thermal Resistance** | Approx. 3.20 °C/W (at 200 LFM) | | **RoHS Status** | Compliant | --- ### 2. Key Design Features * **maxiFLOW™ Geometry:** The heat sink features a unique spread-fin design. Unlike standard straight-fin heat sinks, the fins flare outwards, which maximizes the surface area for heat dissipation and improves airflow efficiency in low-pressure drop environments. * **superGRIP™ Attachment:** This model is usually paired with a "superGRIP" frame. This allows for a secure mechanical attachment to the PCB without the need to drill holes, protecting the component and the board from mechanical stress. * **Pre-Applied Thermal Interface Material (TIM):** Most versions come with a high-performance thermal pad or phase-change material already applied to the base, ensuring optimal thermal contact with the chip. --- ### 3. Applications and Usage This heat sink is intended for small to medium-sized Integrated Circuits (ICs) that generate significant heat. Common use cases include: 1. **Network Switches/Routers:** Cooling ASICs and FPGAs. 2. **Power Supplies:** Managing heat in high-density power modules. 3. **Telecom Equipment:** Used in base stations or high-speed data transmission hardware. --- ### 4. Selection Criteria When integrating the ATS-61270W-C2-R0 into a design, engineers must consider the **CFM (Cubic Feet per Minute)** of the system's cooling fans. Thermal resistance decreases as airflow velocity increases, as shown in the performance curve: ```text Airflow (LFM) | Thermal Resistance (°C/W) ----------------------------------------- 200 | 3.20 400 | 2.30 600 | 1.80 ```
