The **ATS-18B-05-C3-R0** is a high-performance electronic thermal management component. Specifically, it is a **Heat Sink** designed for cooling integrated circuits (ICs) and other electronic components. --- ### 1. Technical Specifications The part number follows the Advanced Thermal Solutions (ATS) nomenclature, which defines its physical and thermal characteristics. | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. | | **Series** | maxiFLOW™ | | **Attachment Method** | pushPIN™ | | **Material** | Aluminum (Blue Anodized) | | **Thermal Resistance** | 11.90°C/W (at 100 LFM) | | **Dimensions (L x W)** | 40mm x 40mm | | **Height** | 25mm | | **Fin Pattern** | Fine Pitch (High Surface Area) | --- ### 2. Key Features and Parts #### A. The Heat Sink Body The body is constructed from extruded aluminum with a **Blue Anodized** finish. This finish is not just for aesthetics; it provides: * **Increased Emissivity:** Improves radiant heat transfer. * **Corrosion Resistance:** Protects the aluminum from environmental degradation. * **Electrical Insulation:** The oxide layer is non-conductive. #### B. The pushPIN™ Attachment System Unlike traditional adhesive-based heat sinks, the "R0" designation usually refers to a specific mounting kit. * **Spring-Loaded Pins:** These provide consistent pressure (Pre-assembled with springs). * **Brass/Plastic Pins:** Used to secure the heat sink through pre-drilled holes in the PCB. * **Reliability:** This mechanical connection is more vibration-resistant than thermal tape. #### C. Thermal Interface Material (TIM) This specific model typically comes with **T766** or a similar high-performance thermal pad/grease pre-applied to the base. This fills the microscopic air gaps between the component (CPU/GPU) and the heat sink. --- ### 3. Usage Context This part is commonly found in: 1. **Telecommunications:** Cooling high-speed processors in switches and routers. 2. **Embedded Systems:** Industrial PCs where vertical space (25mm) is available. 3. **Power Electronics:** Dissipating heat from MOSFETs or Power Modules. ---
