The **ATS-18D-49-C2-R0** is a high-performance thermal management component, specifically a **Heat Sink**, manufactured by Advanced Thermal Solutions, Inc. (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors to prevent thermal throttling or damage. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics: | Property | Specification | Details | | :--- | :--- | :--- | | **Type** | push-PIN™ Heat Sink | Mechanical attachment system | | **Material** | Aluminum | Lightweight with high thermal conductivity | | **Finish** | Blue Anodized | Increases surface emissivity and corrosion resistance | | **Dimensions** | 25mm x 25mm x 20mm | Square footprint with 20mm height | | **Fin Type** | Fine Pitch / Straight | Optimized for high-airflow environments | | **Thermal Resistance** | 5.41 °C/W (@ 100 LFM) | Rate of heat transfer efficiency | --- ### 2. Key Electronic Features #### A. Attachment Mechanism (push-PIN™) Unlike adhesive-based heat sinks, this model uses a **push-PIN™** system with a flexible spring. * **Benefits:** Provides consistent pressure for better thermal interface material (TIM) contact. * **Reliability:** Resistant to vibration and shock, making it suitable for industrial electronics. #### B. Thermal Performance The unit is designed for "Flow-Thru" cooling. As air moves through the fins, the aluminum absorbs heat from the component and releases it into the air stream. * **Convection:** At 100 LFM (Linear Feet per Minute), it provides a resistance of 5.41 °C/W. * **High Velocity:** At 700 LFM, the resistance drops significantly, allowing for high-density power dissipation. #### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates that the part comes with **ATS-PPS-02** or a similar pre-applied phase-change material or thermal pad, ensuring a low-resistance path between the component and the heat sink. --- ### 3. Typical Applications * **BGA (Ball Grid Array) Cooling:** Used for small processors or chipsets. * **Power Modules:** Cooling MOSFETs or voltage regulators. * **Telecommunications:** Cooling chips in routers, switches, and base stations. * **Embedded Systems:** Industrial PCs where space is limited but cooling is critical. ---
