The **ATS-20B-101-C2-R0** is a high-performance electronic thermal management component, specifically an aluminum heat sink designed for cooling integrated circuits (ICs) and other electronic components. --- ### 1. Technical Specifications The part number follows a specific nomenclature from the manufacturer, **Advanced Thermal Solutions (ATS)**. | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 45mm x 45mm x 30mm | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 6.69°C/W (Unducted Flow @ 200 LFM) | | **Fin Style** | Straight Fin | | **Compliance** | RoHS Compliant | --- ### 2. Design and Components This part is not just a block of metal; it is a mechanical assembly consisting of three main electronic cooling elements: #### A. The Heat Sink Body * **Material:** Made of high-grade aluminum for excellent thermal conductivity. * **Fin Geometry:** Features a "Straight Fin" design. This is optimized for systems with a clear directional airflow (like a chassis fan). * **Surface Treatment:** Blue anodized finish, which protects against corrosion and slightly increases emissivity for better radiant heat transfer. #### B. The pushPIN™ Attachment * This specific model uses the **pushPIN™** system instead of thermal adhesive. * It consists of a brass or plastic pin and a high-performance compression spring. * **Benefit:** It provides consistent pressure (TIM - Thermal Interface Material compression), ensuring maximum contact between the heat sink and the chip. #### C. Thermal Interface Material (TIM) * The "R0" suffix usually indicates the inclusion of a pre-applied thermal interface material (typically **T766** or similar). * This fills microscopic air gaps between the component and the heat sink to lower thermal resistance. --- ### 3. Application Use Cases This heat sink is typically found in the following electronic environments: 1. **Telecommunications:** Cooling high-speed processors in routers and switches. 2. **Embedded Systems:** Industrial PCs where high-profile cooling is required. 3. **Power Electronics:** Dissipating heat from MOSFETs or power regulators. --- ### 4. Performance at Airflow The efficiency of this part is highly dependent on the velocity of air moving through the fins: | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 10.22 | | 200 (1.0 m/s) | 6.69 | | 400 (2.0 m/s) | 4.14 | | 600 (3.0 m/s) | 3.23 |
