The part number **ATS-03D-79-C2-R0** refers to a high-performance **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). This component belongs to the "pushPIN™" family, designed for cooling electronic integrated circuits (ICs) and surface-mount devices (SMD). ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Type** | pushPIN™ (Spring-loaded pins) | | **Heat Sink Type** | Fine Pitch (Square Fin) | | **Dimensions (L x W x H)** | 25.0mm x 25.0mm x 30.0mm | | **Thermal Resistance** | 2.63 °C/W (at 100 LFM) | --- ### 2. Physical Design and Construction * **Fin Pattern:** This model uses a **Fine-Pitch** fin design. This maximizes the surface area within a small 25mm footprint, making it ideal for high-density PCB layouts where airflow is available but space is limited. * **Material:** It is made of lightweight aluminum for rapid heat dissipation. * **Thermal Interface Material (TIM):** The "R0" suffix typically indicates that the part comes with a pre-applied **T766 Phase Change Material**, which ensures high thermal conductivity between the component and the heat sink. ### 3. Attachment Mechanism (pushPIN™) The "pushPIN™" system is a specialized mounting hardware included with this part. It consists of: 1. **Brass or Plastic Pins:** Designed to fit into industry-standard holes on the PCB. 2. **Compression Springs:** These provide precise, constant pressure on the electronic component (CPU, FPGA, etc.), ensuring optimal thermal contact without damaging the silicon die or the board. ### 4. Thermal Performance Thermal resistance varies based on the airflow (measured in Linear Feet per Minute - LFM): | Airflow (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 100 | 0.5 | 2.63 | | 200 | 1.0 | 1.70 | | 300 | 1.5 | 1.43 | | 400 | 2.0 | 1.28 | --- ### 5. Part Number Decoding The part number can be broken down to understand its features: * **ATS:** Manufacturer (Advanced Thermal Solutions) * **03:** Product Series * **D:** Attachment Style (Specific pin type) * **79:** Dimensions/Geometry code * **C2:** Material/Fin finish (Blue Anodized) * **R0:** Packaging and Thermal Interface Material (TIM)
