The **ATS-03D-202-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the **pushPIN™** series, designed to provide efficient cooling for electronic components like CPUs, GPUs, and power transistors. --- ## 1. Technical Specifications The following table summarizes the key physical and thermal properties of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance (Flowing)** | 14.83 °C/W @ 100 LFM | | **Thermal Resistance (Static)** | 23.97 °C/W | | **Dimensions (L x W x H)** | 45.00mm x 45.00mm x 15.00mm | | **Pitch** | Fine Pitch | | **Pattern** | XC-CUT | --- ## 2. Key Electronic & Mechanical Components ### A. The Heat Sink Body * **Material:** Made from high-grade aluminum for optimal heat conductivity. * **XC-CUT Design:** The fins are designed with an XC-CUT pattern, which enhances airflow across the surface area, making it ideal for high-density electronic assemblies. * **Fine Pitch:** The spacing between the fins is narrow, maximizing the surface area for heat dissipation within a small footprint (45mm x 45mm). ### B. The pushPIN™ Attachment System Instead of using messy adhesives or simple clips, this model uses a specialized mechanical attachment: * **Spring-Loaded Bolts:** These provide a precise amount of "Firm Tension" to ensure the heat sink remains in constant contact with the electronic chip. * **Compression Springs:** They prevent the heat sink from shifting during vibration or shipping, which is critical for industrial or automotive electronics. ### C. Thermal Interface Material (TIM) * **Pre-applied Coating:** This specific model usually comes with a pre-applied high-performance thermal interface material (T766) on the base. This eliminates the air gaps between the chip and the heat sink, ensuring efficient heat transfer. --- ## 3. Thermal Performance Comparison The effectiveness of this part depends heavily on the airflow (measured in Linear Feet per Minute - LFM): | Air Velocity (LFM) | 100 | 200 | 300 | 400 | 500 | | :--- | :--- | :--- | :--- | :--- | :--- | | **Thermal Res (°C/W)** | 14.83 | 10.55 | 8.73 | 7.63 | 6.87 | --- ## 4. Application Use Cases 1. **Network Switches:** Cooling ASICs that process high volumes of data. 2. **Embedded Systems:** Used in industrial PCs where space is limited but heat generation is high. 3. **Power Supplies:** Dissipating heat from MOSFETs and voltage regulators.
