The **ATS-04F-185-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "pushPIN™" family, designed for cooling electronic components such as CPUs, GPUs, and other high-power ICs. --- ## 1. Technical Specifications The following table outlines the physical and thermal properties of the component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W x H)** | 40mm x 40mm x 30mm | | **Thermal Resistance** | 3.35°C/W (at 100 LFM) | | **Fin Pattern** | Cross-cut (to optimize airflow) | --- ## 2. Key Features and Components ### A. Fin Design * **Structure:** The "04F" series features a cross-cut fin design. This improves the turbulence of the air passing through the fins, allowing for better heat dissipation compared to straight-line fins. * **Surface Area:** The 30mm height provides a significant surface area for heat transfer to the ambient air. ### B. The pushPIN™ Attachment System This heat sink uses a proprietary push-pin system rather than adhesive or standard screws: * **Compression Spring:** Ensures consistent pressure (force) on the component to maximize thermal interface material (TIM) performance. * **Pins:** Usually made of brass or plastic, these snap into pre-drilled holes in the PCB. ### C. Thermal Interface Material (TIM) * The part number usually indicates it comes with **T766** pre-applied thermal phase-change material or grease. This ensures no air gaps exist between the chip and the heat sink base. --- ## 3. Performance Analysis Thermal resistance is the measure of how well the heat sink resists the flow of heat. A lower value is better. | Airflow (LFM) | 100 | 200 | 300 | 400 | 500 | | :--- | :--- | :--- | :--- | :--- | :--- | | **Thermal Resistance (°C/W)** | 3.35 | 1.98 | 1.62 | 1.44 | 1.31 | --- ## 4. Part Number Breakdown The nomenclature follows a specific logic: * **ATS:** Advanced Thermal Solutions * **04:** Heat Sink Series * **F:** Fin configuration (Cross-cut) * **185:** Specific size/footprint code * **C2:** Material/Thermal performance grade * **R0:** ROHS compliant / Revision code ---
