The **ATS-18B-71-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power transistors. --- ### 1. Technical Specifications | Parameter | Details | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Product Type** | Heat Sink | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded attachment) | | **Thermal Resistance** | 6.69°C/W (at 100 LFM) | | **Dimensions** | 45mm x 45mm | | **Height (Profile)** | 30mm | --- ### 2. Design Characteristics The part belongs to the **pushPIN™** series, which is characterized by several key design features: * **Fins:** It utilizes a **cross-cut** or **straight fin** design (depending on the specific sub-series) to increase surface area for heat exchange with the air. * **Attachment Mechanism:** The `pushPIN™` system ensures consistent pressure between the heat sink and the electronic component, optimizing thermal transfer. It typically includes a compression spring and a plastic or metal pin that snaps into the PCB. * **Thermal Interface Material (TIM):** This part usually comes pre-applied with a thermal pad or paste (such as T766) to ensure there are no air gaps between the chip and the aluminum base. --- ### 3. Part Number Breakdown Understanding the nomenclature helps identify the exact features: 1. **ATS-18B**: Identifies the base series and family. 2. **71**: Refers to the specific fin geometry and height configuration. 3. **C2**: Indicates the material and finish (Blue Anodized Aluminum). 4. **R0**: Refers to the packaging and revision status. --- ### 4. Application Use Cases This heat sink is commonly used in environments where **forced air cooling** (fans) is present. Typical applications include: * Embedded computing systems. * Telecommunications equipment. * Network switches and routers. * Power supply modules.
