The **ATS-17D-46-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "pushPIN™" series, designed for precision cooling of integrated circuits (ICs) and other surface-mount components. --- ## 1. Technical Specifications The following table outlines the physical and thermal characteristics of this specific part: | Parameter | Specification | | :--- | :--- | | **Series** | pushPIN™ | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W)** | 25mm x 25mm | | **Height (H)** | 25mm | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Thermal Resistance (Unducted)** | 11.74 °C/W @ 100 LFM | | **Thermal Resistance (Ducted)** | 2.45 °C/W @ 100 LFM | | **Pitch** | Fine-Pitch | --- ## 2. Component Breakdown ### A. The Heat Sink Body The core of the component is made from high-grade aluminum. It utilizes a **Fine-Pitch** fin design, which maximizes the surface area for heat dissipation within a compact 25mm footprint. This is ideal for high-density PCB layouts where space is limited. ### B. The pushPIN™ Attachment System Unlike adhesive-based heat sinks, the ATS-17D-46-C2-R0 uses a mechanical attachment system consisting of: * **Plastic/Brass Pins:** Inserted through pre-drilled holes in the PCB. * **Compression Springs:** Provide precise, consistent pressure (force) to ensure optimal contact between the heat sink and the component (CPU/GPU/ASIC). ### C. Thermal Interface Material (TIM) The part number suffix typically indicates that the unit comes with a **pre-applied Thermal Interface Material**. This eliminates the need for manual thermal paste application, ensuring a uniform layer for better conductivity. --- ## 3. Part Number Decoder Understanding the "ATS-17D-46-C2-R0" nomenclature: | Segment | Meaning | | :--- | :--- | | **ATS** | Advanced Thermal Solutions (Manufacturer) | | **17D** | Specific series/designator for pushPIN assembly | | **46** | Specific fin geometry and dimension code | | **C2** | Thermal Interface Material (e.g., T766) and color | | **R0** | Revision/Packaging code | --- ## 4. Key Advantages 1. **Mechanical Reliability:** The push-pin design prevents the heat sink from shifting or falling off due to vibration or shock. 2. **Ease of Installation:** No specialized tools are required for the "push" mechanism, reducing assembly time in manufacturing. 3. **Efficiency:** The "Blue Anodized" finish isn't just for aesthetics; it provides a layer of protection against corrosion and slightly improves radiant heat transfer.
