The **ATS-03F-73-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 components like CPUs, GPUs, and high-power chipsets. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Fin Type** | Straight | | **Dimensions (L x W x H)** | 45mm x 45mm x 20mm | | **Attachment Method** | Push-Pin (Plastic) with Compression Spring | | **Thermal Interface Material (TIM)** | T412 (Pre-applied) | | **Thermal Resistance** | 14.80°C/W (at 1.0 m/s flow) | --- ### 2. Physical Design Components * **The Heat Sink Body:** Constructed from high-quality aluminum to ensure efficient heat dissipation from the component surface to the surrounding air. * **Fin Geometry:** Features a straight-fin design. This is optimized for airflow patterns generated by nearby fans, allowing air to pass through the channels and carry heat away. * **Attachment Mechanism:** Uses a **Push-Pin** system. This consists of a plastic pin and a spring. The spring provides specific "Load" or pressure, ensuring the heat sink stays in firm contact with the electronic chip for maximum heat transfer. * **Thermal Interface Material (TIM):** It comes pre-applied with **T412**, a high-performance thermal pad/paste. This fills microscopic air gaps between the chip and the heat sink base. --- ### 3. Electronic Application Use Cases This part is typically found in the following electronic environments: 1. **High-Speed Computing:** Cooling of Northbridge/Southbridge chips or FPGAs. 2. **Networking Hardware:** Used on routers and switches where high-speed data processing generates significant localized heat. 3. **Power Supplies:** Cooling of voltage regulators or power transistors. 4. **Embedded Systems:** Industrial PCs where mechanical stability (vibration resistance) is required via the push-pin mounting. --- ### 4. Thermal Performance Data *Measured in °C/W (Degrees Celsius per Watt). Lower values indicate better cooling performance.* | Air Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | | 1.0 (LFM 200) | 14.80 | | 2.0 (LFM 400) | 5.50 | | 3.0 (LFM 600) | 3.80 |
