The **ATS-18F-206-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "pushPIN™" series designed for cooling semiconductor components such as CPUs, GPUs, or high-power ASICs. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Fin Type** | XC-CUT (Cross-Cut) | | **Dimensions (L x W x H)** | 54.00mm x 54.00mm x 15.00mm | | **Thermal Resistance** | 7.71 °C/W (at 100 LFM) | | **Regulatory** | RoHS and REACH Compliant | --- ### 2. Physical Design Features * **XC-CUT Fin Pattern:** The "XC" designation refers to a cross-cut fin geometry. This creates a matrix of pins/fins rather than straight lines, which increases surface area and allows for better airflow in multiple directions (omnidirectional). * **Low Profile:** At only 15mm high, it is designed for space-constrained electronic enclosures where vertical clearance is limited. * **Blue Anodized Coating:** This is not just for aesthetics; the anodization improves the emissivity of the aluminum, slightly enhancing radiant heat transfer and providing corrosion resistance. --- ### 3. Attachment Mechanism (pushPIN™) This part utilizes a specific mechanical attachment system: 1. **Spring-Loaded Bolts:** Provides consistent pressure (Pre-assembled with a 0.7mm to 1.1mm pitch spring). 2. **Brass Components:** The push-pins are typically made of brass or plastic to ensure durability during installation. 3. **Hole Pattern:** It requires a standard 47.00mm x 47.00mm pitch hole layout on the PCB. --- ### 4. Thermal Performance Comparison Thermal resistance ($\theta_{sa}$) determines how efficiently the part moves heat away from the junction. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 7.71 | | 300 (1.5 m/s) | 3.67 | | 500 (2.5 m/s) | 2.67 | | 700 (3.5 m/s) | 2.14 | --- ### 5. Summary of Electronic Application The **ATS-18F-206-C2-R0** is ideal for: * **Networking Equipment:** High-speed routers and switches. * **Power Supplies:** Cooling MOSFETs or power regulators. * **Embedded Systems:** Industrial PCs where mechanical shock resistance (provided by the push-pins) is required.
