The **ATS-18A-95-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). ### 1. Technical Specifications The part is designed for cooling electronic components like CPUs, GPUs, or power modules that generate significant heat. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Product Series** | pushPIN™ | | **Attachment Type** | Push Pin | | **Dimensions (L x W x H)** | 40.00mm x 40.00mm x 25.00mm | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance** | 1.49 °C/W (at 100 LFM) | | **Flow Orientation** | Vertical (Fine Pitch) | --- ### 2. Key Electronic Features #### A. Thermal Resistance (Efficiency) The primary "electronic" function of this part is to lower the junction temperature ($T_j$) of a semiconductor. With a thermal resistance of **1.49 °C/W** at low airflow, it is highly efficient at preventing thermal throttling in high-speed processors. #### B. pushPIN™ Attachment System Unlike adhesive-based heat sinks, this uses a mechanical push-pin system. This is critical for electronics because: * It ensures **consistent pressure** across the TIM (Thermal Interface Material). * It protects the delicate solder joints of the BGA (Ball Grid Array) from mechanical stress. #### C. Fine Pitch Fin Design The fin geometry is optimized for **forced air cooling**. In electronic enclosures where space is tight, the vertical fin arrangement maximizes surface area without obstructing the flow of air from system fans. --- ### 3. Application Examples This part is typically found in: * **Networking Equipment:** Routers and switches. * **Embedded Systems:** Industrial PCs. * **Power Electronics:** Large MOSFET or IGBT modules. ---
