The **ATS-19B-40-C2-R0** is a specific part number for a high-performance **Heatsink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push pin" series designed for cooling electronic components like CPUs, GPUs, and FPGAs. --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Dimensions** | 45mm x 45mm x 15mm | | **Thermal Resistance** | 14.56°C/W (at 100 LFM) | | **Flow Orientation** | Vertical / Omni-directional (Pin Fin) | | **Thermal Interface Material (TIM)** | T766 (High performance) | --- ### 2. Detailed Part Number Breakdown Understanding the nomenclature helps identify the exact features of the electronic part: 1. **ATS**: Manufacturer prefix (Advanced Thermal Solutions). 2. **19B**: Series designation (likely refers to the pin-fin geometry). 3. **40**: Base dimension (approximate width in mm). 4. **C2**: Thermal resistance rating or specific fin configuration. 5. **R0**: RoHS compliance status and manufacturing revision. --- ### 3. Key Electronic Functions While this is a passive mechanical part, its role in an electronic system is critical: * **Heat Dissipation:** It increases the surface area of the component (e.g., a processor), allowing air to carry away heat more effectively via convection. * **Thermal Protection:** By maintaining the Junction Temperature ($T_j$) of a semiconductor below its maximum limit, it prevents thermal throttling or permanent hardware failure. * **Thermal Interface Material (TIM):** The part comes pre-applied with **T766**, a phase-change or grease-like material that fills microscopic air gaps between the chip and the heatsink to minimize contact resistance. --- ### 4. Installation and Mounting The "Push-Pin" mechanism consists of a spring-loaded plastic pin. * **Mechanism:** The pins are pushed through pre-drilled holes in the Printed Circuit Board (PCB). * **Compression:** The internal springs apply a consistent downward force on the component, ensuring the TIM is compressed to its optimal thickness for heat transfer.
