The **ATS-03F-69-C2-R0** is a high-performance electronic thermal management component manufactured by **Advanced Thermal Solutions (ATS)**. It is a heat sink designed primarily for cooling integrated circuits (ICs) and other electronic surface-mount devices. --- ### 1. Technical Specifications The following table highlights the core physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Type** | Push-Pin Heat Sink | | **Material** | Aluminum (Blue Anodized) | | **Dimensions (L x W x H)** | 45mm x 45mm x 20mm | | **Fin Style** | Straight (Cross-cut for airflow versatility) | | **Attachment Method** | Brass Push-Pin (with Compression Spring) | | **Thermal Resistance** | 3.90°C/W (at 200 LFM) | | **Thermal Interface Material** | T766 (Pre-applied) | --- ### 2. Key Component Features #### A. The "push-pin" Mounting System The `03F` in the part number indicates a specific push-pin configuration. * **Design:** It uses two plastic or brass push-pins and a spring. * **Benefit:** This provides a consistent, pre-determined pressure (cload) on the processor, which optimizes heat transfer without damaging the PCB or the chip. #### B. Cross-Cut Fin Design Unlike standard straight fins, these fins are cross-cut. * **Omnidirectional Airflow:** This allows the heat sink to be effective regardless of which direction the air is blowing from inside the chassis. * **Turbulence:** The design creates more air turbulence, which breaks up the "boundary layer" of air and improves cooling efficiency. #### C. Thermal Interface Material (TIM) The part comes with **T766** pre-applied to the base. * This is a "Phase Change" material that fills microscopic air gaps between the heat sink and the chip. * It ensures the lowest possible thermal resistance between the heat-generating component and the cooling fins. --- ### 3. Application Use Cases This specific heat sink is typically found in: 1. **Networking Hardware:** Switches, routers, and high-speed modems. 2. **Industrial PCs:** Cooling CPUs or FPGAs in enclosed environments. 3. **Power Electronics:** Cooling high-wattage voltage regulators or power modules. ---
