The **ATS-19F-110-C2-R1** 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 integrated circuits (ICs) and other surface-mount components. --- ### 1. Technical Specifications The part number itself contains a coded breakdown of its physical and thermal characteristics: | Property | Value | | :--- | :--- | | **Component Type** | Push-Pin Heat Sink | | **Material** | Aluminum (AL6063) | | **Fin Type** | XCUT (Cross-cut / Pin Fin) | | **Attachment Method** | Push-Pin with Springs | | **Thermal Resistance** | ~4.40°C/W (at 200 LFM) | | **Dimensions** | 54mm x 54mm x 25mm | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Features and Electronic Roles #### A. The XCUT Fin Design Unlike straight-fin heat sinks, the XCUT design features gaps between fins that allow for **multi-directional airflow**. This is critical in crowded PCB environments where air might not be blowing in a single, predictable direction. #### B. Push-Pin Attachment Mechanism The "19F" series utilizes a mechanical push-pin system. This provides several advantages for electronic assembly: * **Constant Pressure:** The springs ensure that the heat sink maintains a consistent downward force on the chip, optimizing the contact with the Thermal Interface Material (TIM). * **Reliability:** Unlike adhesive tapes, mechanical pins are more resistant to vibration and high-temperature cycling. * **Ease of Installation:** It allows for quick assembly in a production environment via pre-drilled holes in the PCB. #### C. Thermal Interface Material (T766) The "C2" suffix typically denotes that the part comes with **T766** phase-change material. In electronics, the microscopic air gaps between a chip and a heat sink act as insulators. The T766 material fills these gaps to ensure maximum heat transfer efficiency. --- ### 3. Application Examples This specific heat sink is typically used for cooling high-power electronic components such as: * **CPUs/GPUs:** Small form factor processors or embedded systems. * **FPGAs:** Field Programmable Gate Arrays that generate significant heat during high-speed processing. * **ASICs:** Application-specific integrated circuits used in networking or telecommunications.
