The **ATS-20F-45-C3-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heatsink**. These parts are designed to dissipate heat from integrated circuits (ICs), such as CPUs, GPUs, or FPGAs, ensuring they remain within safe operating temperatures. Below is a detailed breakdown of its electronic and physical specifications. --- ### 1. Technical Specifications | Feature | Specification | Details | | :--- | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | Part of the push-pin series | | **Material** | Aluminum | Blue Anodized finish for protection | | **Thermal Resistance** | 15.02° C/W | Measured at natural convection (low airflow) | | **Airflow Path** | Fine-Pitch Fin | Optimized for high-speed air cooling | | **Attachment Method** | Push-Pin / Springs | Provides high pressure for interface efficiency | | **Dimensions** | 25mm x 25mm x 10mm | Compact profile for tight PCB spaces | --- ### 2. Key Components & Design Features #### A. The Fin Geometry (High Performance) The "F" in the part number indicates a **Fine-Pitch** fin design. This increases the total surface area available for heat exchange. In electronic systems with steady airflow (from chassis fans), this allows for significantly better heat dissipation compared to standard extruded heatsinks. #### B. Attachment Mechanism: Push-Pins & Springs Unlike adhesive-based heatsinks, the ATS-20F-45-C3-R0 uses a mechanical attachment system: * **Push-Pins:** These snap into pre-drilled holes in the PCB. * **Compression Springs:** These ensure constant, even pressure across the surface of the electronic chip. This is critical for maintaining a thin, consistent layer of Thermal Interface Material (TIM). #### C. Thermal Interface Material (TIM) This specific part number typically comes pre-applied with **ATS-PPS-11**, a high-performance phase-change thermal pad. * **Function:** It fills microscopic air gaps between the chip and the heatsink base to maximize heat transfer. --- ### 3. Application Use Cases This part is commonly found in the following electronic environments: 1. **Telecommunications:** Networking switches and routers where small, high-heat chips are densely packed. 2. **Embedded Systems:** Industrial PC boards where vibration resistance (provided by push-pins) is required. 3. **Power Electronics:** Compact voltage regulators or specialized controllers. --- ### 4. Part Number Breakdown To better understand the series, here is how the code is structured: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **20:** Series identifier. * **F:** Fin pitch style (Fine). * **45:** Specific dimension/configuration code. * **C3:** Material/Thermal performance grade. * **R0:** RoHS compliance and revision status.
