The **ATS-18F-40-C2-R0** is a high-performance electronic thermal management component, specifically a **Heatsink** manufactured by **Advanced Thermal Solutions (ATS)**. It belongs to the *Blue Ice* series and is designed for efficient cooling of semiconductors and integrated circuits (ICs). --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Spring Type** | Compression Spring | | **Thermal Resistance** | 1.21 °C/W (at 200 LFM) | | **Dimensions (L x W x H)** | 40mm x 40mm x 25mm | | **Fin Style** | Straight Fin | --- ### 2. Breakdown of the Part Number The part number follows a specific nomenclature used by ATS to identify the component's features: - **ATS-18**: Refers to the specific series/model family. - **F**: Denotes the Fin pitch or density. - **40**: Represents the base dimensions (40mm square). - **C2**: Indicates the thermal interface material (TIM) or specific coating (Blue Anodized). - **R0**: Refers to the revision code or packaging status (usually RoHS compliant). --- ### 3. Key Component Features #### A. Push-Pin Mounting This part utilizes a push-pin attachment mechanism. - **Mechanism:** Plastic pins with integrated springs are pushed through pre-drilled holes in the PCB. - **Benefit:** It provides a secure, consistent downward force on the component, ensuring optimal contact with the heat source while allowing for easy installation. #### B. Material and Coating - **Aluminum (6063):** Chosen for its high thermal conductivity and lightweight properties. - **Blue Anodizing:** This is not just for aesthetics; the anodized layer provides electrical insulation and improves corrosion resistance. #### C. High Performance Fins The straight-fin design is optimized for **forced air cooling** (environments with fans). The spacing between fins is calculated to minimize pressure drop while maximizing the surface area available for heat dissipation. --- ### 4. Applications The ATS-18F-40-C2-R0 is commonly used in: 1. **Network Switches/Routers:** Cooling ASICs and high-speed processors. 2. **Power Supplies:** Dissipating heat from MOSFETs and voltage regulators. 3. **Embedded Systems:** Protecting industrial PCs from thermal throttling.
