The **ATS-03B-191-C2-R0** is a high-performance **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the **push-pin** attachment series designed for cooling electronic components such as CPUs, GPUs, and other high-heat integrated circuits. --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Brass) | | **Dimensions (L x W x H)** | 45mm x 45mm x 30mm | | **Thermal Resistance** | 2.90°C/W (at 200 LFM) | | **Fin Style** | Straight (High-flow) | | **Spring Type** | Compression Spring | --- ### 2. Electronic Application & Performance This component is vital for thermal management in dense electronic assemblies. Its performance varies based on the airflow (LFM - Linear Feet per Minute) within the enclosure: * **Heat Dissipation:** It is designed to transfer heat away from the semiconductor die to the surrounding air. * **Airflow Sensitivity:** * **Unducted Flow:** 2.90°C/W @ 200 LFM. * **High Velocity:** Resistance drops significantly as airflow increases, improving cooling efficiency. * **Thermal Interface Material (TIM):** The "R0" suffix typically denotes that it comes with a pre-applied thermal interface material (like T766) to ensure low thermal resistance between the chip and the heat sink. --- ### 3. Component Breakdown #### A. The Fin Array The straight-fin design is optimized for environments where the direction of the airflow is consistent. The aluminum construction provides a high strength-to-weight ratio and excellent thermal conductivity. #### B. The Push-Pin Mechanism The hardware includes brass push-pins and steel springs. This provides: 1. **Uniform Pressure:** Ensures consistent contact with the electronic component. 2. **Ease of Assembly:** Quick installation through pre-drilled holes in the PCB. 3. **Durability:** The spring-loaded mechanism compensates for thermal expansion and vibration. #### C. Anodized Coating The **Blue Anodized** finish is not just aesthetic; it provides: * Increased surface emissivity (better radiation cooling). * Corrosion resistance. * Electrical insulation to prevent short circuits if a loose wire touches the sink. ---
