The **ATS-18F-46-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors to prevent thermal throttling or hardware failure. --- ## 1. Technical Specifications Below are the primary physical and thermal characteristics of the part: | Characteristic | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Material** | Aluminum (AL6063) | | **Dimensions (L x W)** | 30.00 mm x 30.00 mm | | **Height (H)** | 25.00 mm | | **Fin Style** | Straight Fin | | **Attachment Method** | Push-Pin (Spring Loaded) | | **Thermal Resistance** | 11.87°C/W (at 100 LFM) | | **Finish** | Blue Anodized | --- ## 2. Key Components & Features ### A. The Heat Sink Body * **Material:** Made from Aluminum 6063, which offers a balance of high thermal conductivity and structural integrity. * **Fin Geometry:** It uses a straight-fin design. This is optimized for **forced-air cooling** (airflow from a fan) to maximize surface area contact with the air. ### B. The Attachment Mechanism (pushPIN™) This part utilizes a specific mounting system rather than adhesive tape: * **Push-Pins:** Plastic or brass pins that lock into pre-drilled holes on the PCB. * **Springs:** Provides consistent **pressure** (interface force) between the heat sink and the component, ensuring the best possible heat transfer. ### C. Thermal Interface Material (TIM) * The "-R0" suffix typically denotes that the part comes with **pre-applied thermal interface material**. This fills microscopic air gaps between the chip and the heat sink, significantly reducing thermal resistance. --- ## 3. Performance Analysis (Thermal) The efficiency of this part depends heavily on the airflow (measured in Linear Feet per Minute - LFM): | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 11.87 | | 300 (1.5 m/s) | 5.00 | | 500 (2.5 m/s) | 3.60 | *Interpretation: The higher the airflow, the lower the thermal resistance, meaning the component stays cooler.* --- ## 4. Common Applications * **Networking Equipment:** Routers, switches, and small-form-factor servers. * **Embedded Systems:** Industrial PCs and controllers where space is limited. * **Power Supplies:** Cooling voltage regulators or MOSFETs that generate significant heat during operation.
