The **ATS-18F-49-C3-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heat sink**. It is designed to dissipate heat from electronic components like CPUs, GPUs, or FPGAs to prevent thermal throttling or hardware failure. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this specific model: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Brass) | | **Spring Type** | Compression Spring | | **Dimensions** | 30mm x 30mm x 10mm | | **Fin Style** | Straight (Standard) | | **Thermal Resistance** | 11.90° C/W (@ 100 LFM) | | **Thermal Interface Material (TIM)** | T412 (Chomerics) | --- ### 2. Breakdown of the Part Number The part number follows a specific nomenclature used by Advanced Thermal Solutions: * **ATS**: Manufacturer (Advanced Thermal Solutions). * **18**: Represents the product series (Heat Sink family). * **F**: Likely indicates the fin pattern or density. * **49**: Specific dimensional code for the 30mm x 30mm footprint. * **C3**: Indicates the height and thermal performance tier. * **R0**: RoHS compliance status and revision level. --- ### 3. Key Electronic Functions #### A. Thermal Dissipation This part acts as a passive heat exchanger. It increases the surface area of the component it is attached to, allowing air (moved by a fan or natural convection) to carry away heat more efficiently. #### B. Push-Pin Attachment Mechanism Unlike adhesive-based heat sinks, the `ATS-18F-49-C3-R0` uses a mechanical push-pin system: * **Reliability:** Provides consistent pressure across the component surface. * **Installation:** Requires pre-drilled holes in the PCB. * **Vibration Resistance:** The compression springs ensure the heat sink remains in contact with the chip even in high-vibration environments (e.g., industrial or automotive use). #### C. Pre-applied TIM (Thermal Interface Material) The unit comes with **T412** pre-applied to the base. This is a crucial electronic "part" because it fills microscopic air gaps between the heat sink and the semiconductor, significantly lowering thermal resistance. --- ### 4. Typical Applications * **Embedded Systems:** Cooling small-form-factor processors. * **Telecommunications:** Cooling ASICs in networking switches or routers. * **Power Supplies:** Dissipating heat from high-speed switching transistors.
