The **ATS-18A-177-C2-R0** is a high-performance electronic thermal management component, specifically a **Pin Fin Heat Sink** designed by Advanced Thermal Solutions (ATS). It is engineered for cooling electronic components like CPUs, GPUs, and other high-power semiconductors. --- ## 1. Technical Specifications The following table outlines the physical and thermal characteristics of this specific part: | Characteristic | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W x H)** | 35.00mm x 35.00mm x 20.00mm | | **Thermal Resistance (Unducted Flow)** | 6.18 °C/W @ 100 LFM | | **Thermal Resistance (Ducted Flow)** | 1.89 °C/W @ 100 LFM | | **Fin Style** | Pin Fin (cross-cut) | --- ## 2. Key Electronic Features ### A. pushPIN™ Attachment System The "R0" in the part number indicates the use of the ATS pushPIN™ system. This is critical for electronic PCB assembly because: * It ensures a **precise pressure** is applied to the electronic component (TIM - Thermal Interface Material). * It features a built-in spring mechanism that prevents over-tightening, which could crack a delicate silicon die. ### B. Thermal Interface Material (TIM) The unit typically comes with **T766** pre-applied. This is a high-conductivity phase-change material or thermal grease that fills microscopic air gaps between the chip and the heat sink to maximize heat transfer. ### C. Pin Fin Geometry Unlike traditional straight-fin heat sinks, the pin-fin design is **omni-directional**. In complex electronic enclosures where airflow direction may be unpredictable or turbulent, pin fins provide better cooling efficiency because they allow air to enter the fin array from any angle. --- ## 3. Applications This part is commonly found in the following electronic environments: 1. **Telecommunications:** Cooling for high-speed routers and switches. 2. **Embedded Systems:** Industrial PCs and automation controllers. 3. **Power Electronics:** Cooling for MOSFETs and IGBT modules. ---
