The **ATS-19B-46-C2-R0** is a high-performance electronic thermal management component, specifically a **Heatsink** designed for cooling integrated circuits (ICs) and other electronic components. It is manufactured by *Advanced Thermal Solutions (ATS)*. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W x H)** | 25.00mm x 25.00mm x 25.00mm | | **Fin Style** | High-flow Fin Pattern (Cross-cut) | | **Thermal Resistance** | 11.57°C/W (at 100 LFM) | --- ### 2. Key Electronic Components #### A. The pushPIN™ Attachment System Unlike traditional adhesive-based heatsinks, this part uses a **pushPIN™** system. This consists of: * **Brass/Steel Pins:** These go through pre-drilled holes in the PCB. * **Compression Springs:** These ensure a consistent, pre-determined pressure is applied to the component, optimizing thermal transfer without damaging the silicon. #### B. Thermal Interface Material (TIM) The "R0" suffix usually indicates the inclusion of a pre-applied thermal interface material. * **Purpose:** Fills microscopic air gaps between the heatsink base and the electronic chip. * **Material:** Usually a high-performance phase-change material or thermal pad. #### C. Fin Geometry (Cross-Cut) The heatsink features a **cross-cut** design. In electronics cooling, this allows for: * **Omnidirectional Airflow:** Air can enter from any side, making it ideal for enclosures where airflow direction is inconsistent or crowded with other components. * **Turbulence:** The gaps between fins create more air turbulence, which carries heat away more efficiently than flat surfaces. --- ### 3. Common Applications This part is typically used to cool the following electronic components: 1. **BGA Packages:** Ball Grid Array chips like FPGAs or small CPUs. 2. **Power Converters:** Voltage regulators that generate significant heat in a small footprint. 3. **Network Switches:** High-speed data processing chips that require 25mm height clearance. ---
