## Electronic Component Analysis: ATS-20H-129-C2-R0 The **ATS-20H-129-C2-R0** is a high-performance **Heat Sink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "push pin" series designed for securing thermal management solutions to printed circuit boards (PCBs). ### 1. Technical Specifications The following table summarizes the key physical and thermal properties of this component: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Heat Sink Type** | Push Pin (Cross-Cut) | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 54.00mm x 54.00mm x 20.00mm | | **Thermal Resistance** | 0.86 °C/W (@ 200 LFM) | | **Attachment Method** | Push Pin (Brass) | | **Spring Type** | Compression Spring | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Features and Design * **Cross-Cut Fin Design:** The "high-performance" cross-cut pattern allows for multi-directional airflow. This is critical in dense electronic enclosures where airflow may not be strictly linear. * **Push Pin Attachment:** It uses a brass push pin mechanism with a built-in spring. This ensures consistent pressure on the processor or component, maximizing the effectiveness of the thermal interface material. * **Pre-Applied TIM:** The unit comes with **T766** thermal interface material already applied to the base, reducing assembly time and ensuring a reliable thermal bond between the heat sink and the heat source. * **Material & Coating:** Made from high-grade aluminum for lightweight thermal conductivity, with a blue anodized finish for increased surface area durability and corrosion resistance. --- ### 3. Applications This specific heat sink is typically used for cooling high-heat-generating electronic components, including: 1. **CPUs and GPUs:** In embedded systems or industrial PCs. 2. **ASICs and FPGAs:** Used in telecommunications and data processing equipment. 3. **Power Supplies:** Cooling large power transistors or voltage regulators. --- ### 4. Thermal Performance Comparison Thermal resistance ($R_{th}$) determines how efficiently the heat sink moves heat away from the component. Lower values are better. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 (1.0 m/s) | 0.86 | | 300 (1.5 m/s) | 0.67 | | 400 (2.0 m/s) | 0.57 | | 500 (2.5 m/s) | 0.51 | ---
