The **ATS-20D-59-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It belongs to the **maxiFLOW™** series, designed to provide high thermal performance in restricted airflow environments. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ | | **Thermal Resistance (Flowing Air)** | 6.31 °C/W @ 100 LFM | | **Thermal Resistance (Static)** | 2.50 °C/W @ 400 LFM | | **Dimensions (L x W x H)** | 40mm x 40mm x 20mm | | **Weight** | ~35.0 grams | --- ### 2. Design and Component Breakdown #### A. Fin Geometry (maxiFLOW™) The "59" in the part number refers to a specific fin configuration. The design features a **tapered fin structure**. Unlike standard straight-fin heat sinks, this geometry: * Reduces pressure drop across the sink. * Increases surface area for heat dissipation. * Is optimized for high-density PCB layouts. #### B. The pushPIN™ Attachment System This part uses the **pushPIN™** mounting mechanism rather than thermal adhesive. This includes: * **Spring-loaded pins:** Provide consistent pressure to improve thermal interface material (TIM) performance. * **Compression Springs:** Available in various materials (e.g., brass or plastic) to achieve specific force requirements. * **Reliability:** Ensures the heat sink stays mounted during high-vibration or mechanical shock scenarios. #### C. C2 Material/Finish Code The **C2** suffix indicates the thermal interface and finish: * **Color:** Blue. * **Coating:** Anodized (provides corrosion resistance and improved emissivity). * **Interface:** Usually comes pre-applied with a high-performance **Thermal Interface Material (TIM)** to ensure the gap between the chip and the aluminum is minimized. --- ### 3. Application Use Cases This specific heat sink is typically used for cooling: 1. **ASICs and FPGAs:** Used in networking hardware where high-speed processing generates significant heat. 2. **CPUs/GPUs:** In embedded systems or industrial PCs. 3. **Power Converters:** For managing heat in localized power distribution units on a PCB. --- ### 4. Part Number Breakdown To understand the product family, here is how the SKU is structured: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **20D:** Series/Size identifier. * **59:** Fin configuration/pattern. * **C2:** Finish (Blue Anodized) and Thermal Interface Material. * **R0:** RoHS Compliance/Revision status.
