The **ATS-20F-46-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions Inc.* It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors to prevent thermal throttling or failure. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics: | Property | Value / Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Base Part Number** | ATS-20F-46-C3-R0 | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 25.00mm x 25.00mm x 15.00mm | | **Fin Style** | XCUT (Cross-Cut) | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | ~11.00°C/W (Unducted Flow @ 1.0 m/s) | --- ### 2. Key Electronic Features #### A. XCUT Fin Design The "F" in the part number indicates a specific fin pattern. The **XCUT** design provides multi-directional airflow. Unlike straight-fin heat sinks that require air to move in one specific direction, cross-cut fins allow the heat sink to be effective even if the cooling fan is slightly offset or if the air turbulence is high. #### B. pushPIN™ Attachment This part utilizes a specialized mechanical attachment system. * **Hardware:** It consists of a brass or plastic pin and a stainless steel spring. * **Reliability:** It provides a precise "clamping force" on the electronic chip, ensuring optimal contact with the Thermal Interface Material (TIM) without cracking the silicon die. #### C. Blue Anodized Finish The blue coating is not just for aesthetics. Anodization increases: 1. **Emissivity:** Improves heat radiation. 2. **Corrosion Resistance:** Protects the aluminum from environmental degradation. 3. **Electrical Insulation:** Provides a thin non-conductive layer on the surface of the metal. --- ### 3. Usage Context In an electronic circuit, this part is typically found in: * **Embedded Systems:** Cooling high-speed ARM processors. * **Power Supplies:** Dissipating heat from MOSFETs or Voltage Regulators. * **Telecommunications:** Cooling ASICs in networking switches. --- ### 4. Component Comparison How this part compares to standard extruded heat sinks: ```markdown - Higher Surface Area: The XCUT pattern creates more surface area in a smaller footprint (25x25mm). - Pressure Drop: Lower pressure drop compared to ultra-dense straight fins. - Attachment Speed: pushPIN™ is significantly faster for assembly lines than screw-and-nut mounting. ```
