The **ATS-18D-48-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) Heat Sink** designed for cooling electronic integrated circuits (ICs) and other surface-mount components. ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. | | **Series** | pushPIN™ | | **Thermal Resistance** | 2.29°C/W (@ 100 LFM) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Spring Loaded) | | **Dimensions** | 25mm x 25mm x 25mm | | **Weight** | 30.71 Grams | --- ### 2. Component Breakdown The part number follows a specific nomenclature that describes its physical build: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **18D:** Designates the specific fin pattern and density. * **48:** Refers to the height or specific series variation. * **C2:** Refers to the thermal interface material (TIM) or specific coating (usually T766 or similar). * **R0:** Revision code, indicating the standard production version. --- ### 3. Key Electronic Functions While the heat sink itself is passive (it does not contain circuitry), it is critical for the reliable operation of electronic systems in the following ways: #### A. Thermal Dissipation The primary role is to increase the surface area of a semiconductor (like a CPU, FPGA, or Power MOSFET). By conducting heat away from the silicon die, it prevents **thermal throttling** or permanent damage due to overheating. #### B. Push-Pin Mounting System Unlike adhesive-based heat sinks, the `-R0` series uses a mechanical **Push-Pin** system. This provides: * **Constant Pressure:** Ensures maximum contact between the component and the heat sink. * **Vibration Resistance:** Securely holds the part in place during industrial or automotive vibrations. * **Serviceability:** Allows the heat sink to be removed and reapplied without damaging the PCB. #### C. Optimized Airflow (Fine Pitch Fins) The "18D" designation indicates a specific fin geometry designed for **forced air cooling**. The vertical fins are spaced to minimize pressure drop while maximizing the heat transfer coefficient when a fan is blowing air through the chassis. --- ### 4. Typical Applications This specific size (25mm x 25mm) is commonly used on: * Network Switches and Routers. * Industrial Control Units. * High-speed memory modules. * Embedded computing boards (SBCs).
