## Electronic Component Overview: ATS-20F-37-C2-R0 The **ATS-20F-37-C2-R0** is a high-performance **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It belongs to the **maxiFLOW™** product line, specifically designed for cooling high-power electronic components such as processors, FPGAs, and ASICs. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-20F-37-C2-R0 | | **Component Category** | Thermal Management (Heat Sink) | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 9.12 °C/W (at 200 LFM) | | **Material** | Aluminum (Blue Anodized Finish) | | **Base Dimensions** | 37.00 mm x 37.00 mm | | **Height** | 15.00 mm | | **Fin Style** | maxiFLOW™ (Tapered Fin) | --- ### 2. Design and Functional Elements #### A. The maxiFLOW™ Fin Geometry The "F" in the part number indicates the maxiFLOW™ design. Unlike standard rectangular fins, these fins are tapered. This geometry: * Reduces pressure drop across the heat sink. * Increases surface area for heat dissipation. * Optimizes airflow in constrained spaces. #### B. pushPIN™ Attachment System The **-R0** suffix refers to the attachment mechanism. This model uses a **pushPIN™** system which includes: * **Compression Springs:** Provide precise pressure (load) on the component to ensure optimal thermal interface contact. * **Plastic/Brass Pins:** Secure the heat sink directly to the PCB via pre-drilled holes. #### C. Material and Finish * **Aluminum 6063:** Chosen for its high thermal conductivity and lightweight properties. * **Blue Anodized Coating:** Provides corrosion resistance and increases thermal emissivity. --- ### 3. Thermal Performance Data Performance is measured by Thermal Resistance (°C/W). Lower values indicate better cooling efficiency. | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 (1.0 m/s) | 9.12 | | 400 (2.0 m/s) | 5.38 | | 600 (3.0 m/s) | 4.01 | --- ### 4. Implementation Requirements To use this part effectively in a circuit design, the following are required: 1. **PCB Hole Pattern:** The board must have holes corresponding to the pushPIN™ spacing (standardized for this 37mm frame). 2. **Thermal Interface Material (TIM):** This part usually comes with **ATS-51**, a high-performance thermal pad/grease pre-applied to the base. 3. **Clearance:** A vertical clearance of at least 15mm is required above the component.
