The **ATS-19B-155-C2-R0** is a high-performance electronic thermal management component, specifically a **heat sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power transistors. --- ### 1. Technical Specifications The part number itself follows a specific nomenclature that defines its physical and thermal characteristics: | Feature | Specification | |:---|:---| | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W x H)** | 40.00mm x 40.00mm x 20.00mm | | **Fin Style** | XCUT (Cross-cut) | | **Thermal Resistance** | 5.37°C/W (at 100 LFM) | --- ### 2. Key Electronic Features #### A. XCUT Fin Design Unlike standard straight-fin heat sinks, the **XCUT** design features a cross-cut pattern. This is electronically significant because: * It allows for multi-directional airflow, making it ideal for systems where air may not be traveling in a single linear path. * It increases the surface area for heat exchange without significantly increasing the footprint of the component. #### B. pushPIN™ Attachment System This component uses a specialized mounting system consisting of a brass or plastic pin and a high-performance compression spring. * **Constant Pressure:** Ensures uniform interface pressure between the heat sink and the electronic chip, which is critical for maximizing heat transfer. * **Stability:** Prevents the heat sink from shifting during vibration or shipping, protecting the delicate solder joints of the PCB. #### C. Thermal Interface Material (TIM) The "R0" suffix generally indicates that the part comes pre-applied with a thermal interface material (typically a phase-change material or high-performance grease). This fills the microscopic air gaps between the component and the heat sink. --- ### 3. Thermal Performance Profile The efficiency of this part is measured by its thermal resistance (lower is better). | Airflow (LFM) | Thermal Resistance (°C/W) | |:---:|:---:| | 100 (0.5 m/s) | 5.37 | | 300 (1.5 m/s) | 2.50 | | 500 (2.5 m/s) | 1.91 | --- ### 4. Typical Applications * **Embedded Systems:** For cooling SoCs (System on Chips). * **Networking Hardware:** Switches and routers where airflow is often turbulent. * **Industrial PCs:** Where durability and secure mounting are required.
