The **ATS-16B-49-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 efficient cooling of semiconductor devices like CPUs, GPUs, or high-power transistors. --- ### 1. Technical Specifications The following table summarizes the physical and thermal characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ | | **Dimensions (L x W)** | 25mm x 25mm | | **Height (Fin)** | 15mm | | **Pitch** | Fine Pitch | | **Fin Pattern** | XCUT | --- ### 2. Performance Characteristics Thermal resistance is critical in electronic parts to prevent "thermal throttling" or hardware failure. * **Thermal Resistance (Unducted):** 5.90 °C/W @ 100 LFM * **Thermal Resistance (Ducted):** 2.73 °C/W @ 100 LFM * **Airflow compatibility:** Designed for both natural convection and forced air cooling. --- ### 3. Component Breakdown #### A. The XCUT Design The "XCUT" geometry refers to the fin pattern. Unlike straight fins, XCUT patterns allow for air to enter from multiple directions, making it ideal for compact electronic enclosures where airflow direction might be inconsistent. #### B. The pushPIN™ Attachment Instead of using messy thermal adhesives or simple tapes, this part uses a mechanical push-pin system: * **Compression Spring:** Ensures even pressure across the component (TIM) for maximum heat transfer. * **Plastic/Brass Pins:** Secure the heat sink through pre-drilled holes in the PCB. #### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates that the part comes with a pre-applied thermal interface material (usually **T766**), which fills microscopic air gaps between the heat sink and the electronic chip. --- ### 4. Part Number Decoder Understanding the nomenclature helps in identifying variants: | Segment | Meaning | | :--- | :--- | | **ATS** | Manufacturer (Advanced Thermal Solutions) | | **16B** | Series/Attachment type | | **49** | Dimension/Design code | | **C2** | Material/Thermal performance grade | | **R0** | Finish and TIM (Blue Anodized / T766) |
