The **ATS-19B-19-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **maxiFLOW™** series, designed to provide high cooling performance in constrained spaces. --- ## 1. Technical Specifications The following table details the physical and thermal properties of this specific part number: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (with Blue Anodized Finish) | | **Dimensions (L x W x H)** | 40mm x 40mm x 20mm | | **Thermal Resistance** | 9.77°C/W (at 200 LFM) | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Base Shape** | Square | | **Fin Style** | maxiFLOW (Tapered Fin Design) | --- ## 2. Key Components & Design Features ### A. maxiFLOW™ Fin Geometry Unlike standard straight-fin heat sinks, the maxiFLOW™ design features a **tapered fin** structure. This increases the surface area available for heat dissipation while minimizing the pressure drop, allowing air to flow more effectively through the fins. ### B. pushPIN™ Attachment System This part uses the **pushPIN™** mounting mechanism. It includes: * **Compression Springs:** Provide precise pressure to ensure optimal thermal interface contact. * **Plastic/Brass Pins:** Secure the heat sink directly to pre-drilled holes in the PCB. * **Ease of Assembly:** Allows for quick installation and removal without specialized tools. ### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates that the part comes with a pre-applied **Phase Change Material (PCM)** or high-performance thermal pad. This ensures that the microscopic gaps between the electronic component (like a CPU or FPGA) and the heat sink base are filled, maximizing heat transfer. --- ## 3. Common Applications This heat sink is designed for components that generate significant heat in telecommunications, networking, and industrial computing: * **FPGAs & ASICs:** Cooling high-speed processing chips. * **Power Supplies:** Managing heat in voltage regulators. * **Broadband Systems:** Used in routers and switches where airflow might be limited. ---
