Technical Specifications The following table outlines the physical and thermal characteristics of this specific part number: | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-18A-77-C3-R0 | | **Material** | Aluminum (Black Anodized) | | **Dimensions** | 45mm x 45mm x 20mm | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 9.58°C/W (at 1.0 m/s airflow) | | **Thermal Interface Material (TIM)** | T412 (Pre-applied) | --- ### 2. Breakdown of the Part Number The part number follows a specific nomenclature used by Advanced Thermal Solutions: * **ATS**: Manufacturer (Advanced Thermal Solutions). * **18A**: Refers to the specific series/fin configuration. * **77**: Designates the specific dimensions (45mm x 45mm base). * **C3**: Indicates the height of the heat sink (20mm). * **R0**: Refers to the revision and material finish (typically Black Anodized). --- ### 3. Key Electronic/Mechanical Features #### A. maxiFLOW™ Design The heat sink features a tapered fin design that increases the surface area for heat dissipation while maintaining a low pressure drop. This allows it to perform efficiently in environments with limited airflow. #### B. pushPIN™ Attachment Unlike adhesive-based heat sinks, the **pushPIN™** system uses a flexible, tool-free mounting mechanism. This provides: * Consistent pressure on the electronic component (ensuring better thermal contact). * Secure mechanical stability against vibration and shock. * Easy removal and re-installation during maintenance. #### C. Thermal Interface Material (T412) The "T412" coating is a high-performance thermal pad pre-applied to the base. This material fills microscopic air gaps between the heat sink and the electronic chip, significantly reducing the thermal resistance across the interface. --- ### 4. Applications This part is commonly used in: * **Network Switches/Routers:** Cooling high-traffic processors. * **Power Supplies:** Managing heat in MOSFETs or voltage regulators. * **Industrial PCs:** Ensuring reliability in fanless or high-density enclosures.
