The **ATS-03D-91-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "push pin" series designed for cooling processors and other surface-mount components. ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-03D-91-C3-R0 | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | Push-Pin (Brass) | | **Spring Type** | Compression Spring | | **Thermal Interface Material (TIM)** | T412 (Pre-applied) | | **Dimensions** | 40mm x 40mm x 10mm | | **Fin Style** | Straight Fin | --- ### 2. Physical & Electronic Functionality The primary purpose of this part is to increase the surface area of a heat-generating electronic component (like a CPU, FPGA, or GPU), allowing heat to dissipate into the surrounding air more efficiently. * **Thermal Performance:** It is designed to lower the junction temperature of semiconductors. Its performance varies based on airflow: * **At 200 LFM (Linear Feet per Minute):** Approx 4.90 °C/W thermal resistance. * **At 500 LFM:** Approx 2.70 °C/W thermal resistance. * **The "Push-Pin" Mechanism:** This model uses a brass push-pin system. These pins pass through pre-drilled holes in the PCB (Printed Circuit Board). The springs provide a consistent "downward force" (pressure) to ensure maximum contact between the heat sink and the chip. * **Material properties:** The **Blue Anodized** finish is not just for aesthetics; it provides corrosion resistance and improves thermal emissivity. --- ### 3. Usage Context This part is typically found in: * **Telecommunications:** Cooling network switches and routers. * **Embedded Systems:** Industrial PCs or controllers. * **Power Electronics:** Managing heat for high-speed data processing chips. --- ### 4.
