The **ATS-18A-91-C2-R0** is a high-performance electronic thermal management component, specifically a **Heatsink** designed by Advanced Thermal Solutions (ATS). It is part of their "push-pin" series, engineered to provide efficient cooling for integrated circuits (ICs) and other electronic surface-mount components. --- ### 1. Technical Specifications Below are the key physical and thermal properties of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) with Compression Spring | | **Dimension (L x W)** | 40mm x 40mm | | **Height** | 10mm | | **Thermal Resistance** | 21.97°C/W (at 0 LFM) to 1.76°C/W (at 800 LFM) | | **Fin Type** | Straight Fin | --- ### 2. Detailed Part Breakdown #### A. Thermal Performance The heatsink is designed for "forced air" environments. While its performance is modest in natural convection (stationary air), its efficiency increases exponentially as airflow (LFM - Linear Feet per Minute) increases. This makes it ideal for server racks or devices with internal cooling fans. #### B. Attachment Mechanism (Push-Pins) Unlike adhesive-based heatsinks, the **ATS-18A-91-C2-R0** uses a mechanical push-pin system: * **Reliability:** It provides consistent pressure across the component surface, improving heat transfer. * **Ease of Assembly:** It allows for quick installation on pre-drilled PCBs. * **Spring-Loaded:** The brass or plastic springs ensure the heatsink remains in contact with the chip even under mechanical vibration. #### C. Material and Coating * **Aluminum 6063:** Chosen for its excellent thermal conductivity and lightweight properties. * **Blue Anodization:** Not just for aesthetics; the anodized layer provides increased corrosion resistance and electrical insulation, while also slightly improving radiant heat emissivity. --- ### 3. Typical Applications This specific heatsink size and profile (40x40x10mm) are commonly used for: 1. **Processors:** Low-power CPUs or high-speed DSPs (Digital Signal Processors). 2. **Network Hardware:** Cooling ASICs in switches and routers. 3. **Power Electronics:** Cooling MOSFET arrays or large voltage regulators. 4. **FPGAs:** Managing heat on Field Programmable Gate Arrays. ---
