The **ATS-19B-27-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "push-pin" series designed for securing cooling solutions to Printed Circuit Boards (PCBs). ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Product Type** | Heat Sink (Push-Pin Attachment) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 70mm x 45mm x 10mm | | **Fin Type** | Straight Fin | | **Thermal Resistance** | 12.24°C/W (at 200 LFM) | | **Attachment Method** | Push-Pin / Springs | --- ### 2. Breakdown of the Part Number The part number follows a specific nomenclature used by ATS to identify the physical and thermal properties of the component: * **ATS-19B**: Refers to the specific series and family of the heatsink. * **27**: Denotes the size/geometry configuration. * **C2**: Indicates the specific Thermal Interface Material (TIM) and color (usually T766 or similar blue anodized finish). * **R0**: Represents the revision or specific packaging version of the part. --- ### 3. Electronic & Mechanical Functionality #### A. Thermal Dissipation This part is a "passive" cooling component. Its primary function is to increase the surface area of a heat-generating electronic component (such as a CPU, FPGA, or MOSFET). This allows the heat to be transferred into the surrounding air more efficiently via convection. #### B. Mounting Mechanism (Push-Pins) Unlike adhesive-based heat sinks, the **ATS-19B-27-C2-R0** uses a mechanical push-pin system: * **Spring-loaded Pins:** These ensure a consistent and high pressure against the component, which optimizes heat transfer. * **Reliability:** Mechanical mounting is preferred in high-vibration environments where thermal tape or epoxy might fail. #### C. Thermal Interface Material (TIM) The "C2" designation usually implies that the heat sink comes pre-applied with a thermal pad or phase-change material. This fills the microscopic air gaps between the component and the metal of the heat sink to ensure maximum thermal conductivity. --- ### 4. Application Areas * **Telecommunications:** Cooling high-speed data processing chips. * **Computing:** Graphics cards, chipsets, and voltage regulator modules (VRMs). * **Industrial Power Supplies:** Cooling power transistors that generate significant heat during operation.
