The **ATS-19B-170-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** from Advanced Thermal Solutions (ATS). It is part of their "pushPIN™" series, designed for efficient cooling of integrated circuits (ICs) and other heat-generating electronic parts. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal properties. | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum (Al6063) | | **Finish** | Blue Anodized | | **Attachment Type** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 5.44 °C/W (at 100 LFM) | | **Dimensions (L x W x H)** | 30mm x 30mm x 15mm | | **Mounting Hole Pattern** | 35mm x 35mm | | **Spring/Pin Material** | Brass/Steel with Plastic | --- ## 2. Key Electronic Functions While this is a passive mechanical part, its role in electronic systems is critical for stability and longevity. ### Thermal Dissipation The primary function is to transfer heat away from a semiconductor device (like a CPU, FPGA, or MOSFET) into the surrounding air. * **Thermal Interface:** It requires a Thermal Interface Material (TIM), such as thermal paste or a pad, to bridge the microscopic air gaps between the chip surface and the aluminum base. * **Airflow Optimization:** The "C2" design indicates a specific fin pattern (Cross-cut) which allows for better airflow in multiple directions compared to standard straight-fin sinks. ### Attachment Mechanism (pushPIN™) Unlike adhesive-based heat sinks, the **R0** suffix indicates a push-pin attachment system. * **Reliability:** It provides consistent pressure on the electronic component, ensuring optimal thermal contact. * **Vibration Resistance:** The spring-loaded mechanism prevents the heat sink from shifting during mechanical shock or thermal expansion cycles. --- ## 3. Physical Design Attributes ### Fin Profile The heat sink features a **fine-pitch fin design**. This increases the total surface area available for convection without significantly increasing the footprint of the electronic assembly. ### Anodization The **Blue Anodized** finish is not just for aesthetics; it provides: 1. **Corrosion Resistance:** Protects the aluminum from oxidation. 2. **Electrical Insulation:** Provides a thin layer of non-conductive oxide, reducing the risk of short-circuits if the sink accidentally touches nearby traces (though it should still be treated as a metal part). 3. **Emissivity:** Improves heat radiation compared to raw polished aluminum. --- ## 4. Application Use-Cases * **PCB Assemblies:** Used on high-density boards where space is limited but heat output is high. * **Power Supplies:** Cooling voltage regulators or power transistors. * **Embedded Systems:** Maintaining safe operating temperatures for ARM processors or DSPs in industrial enclosures.
