The **ATS-03F-207-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heat sink**. It is designed to dissipate heat from integrated circuits (ICs), such as CPUs, GPUs, or FPGAs, ensuring they remain within safe operating temperature limits. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics of the device: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (Blue Anodized) | | **Attachment Type** | Push-Pin (Plastic or Brass) | | **Base Dimensions** | 54.00mm x 54.00mm | | **Height (Fin)** | 25.00mm | | **Thermal Resistance** | 6.39°C/W (at 100 LFM) | | **Thermal Interface (TIM)** | T766 (Pre-applied Phase Change Material) | --- ### 2. Physical Design & Components The "electronic" functionality of this part is passive, relying on thermodynamics to protect active electronic components. #### A. Fin Geometry (XC-Cut) The unit features a **cross-cut (XC)** pattern. This creates a matrix of pins/fins rather than straight extrusions, allowing for multidirectional airflow. This is critical in crowded PCB environments where air might not flow in a single linear path. #### B. Push-Pin Attachment Mechanism Instead of using messy adhesives or permanent solder, this part uses a mechanical **Push-Pin and Spring** system: * **Compression Spring:** Provides consistent pressure to ensure the base of the heat sink remains in flush contact with the chip. * **Plastic/Brass Pin:** Snaps into pre-drilled holes in the PCB. #### C. Thermal Interface Material (TIM) The base comes pre-coated with **T766**. This material fills the microscopic air gaps between the heat sink and the electronic component, significantly reducing thermal resistance and improving heat transfer efficiency. --- ### 3. Usage Context This part is typically used in industrial and high-reliability electronic applications: * **Networking Gear:** Routers and switches with high-speed processing chips. * **Power Supplies:** Cooling MOSFETs or power regulators. * **Embedded Systems:** Industrial PCs where mechanical stability (vibration resistance) is required. --- ### 4. Thermal Performance Comparison Thermal resistance decreases as airflow (LFM - Linear Feet per Minute) increases: | Airflow (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 100 | 0.5 | 6.39 | | 300 | 1.5 | 2.57 | | 500 | 2.5 | 1.82 | ---
