The **ATS-18B-93-C2-R0** is a high-performance electronic component specifically designed for thermal management. It is a heat sink from the **Advanced Thermal Solutions (ATS)** "maxiFLOW" series, intended to dissipate heat from integrated circuits (ICs) and other electronic components. --- ### 1. Technical Specifications Below are the primary technical characteristics of the ATS-18B-93-C2-R0: | Feature | Specification | | :--- | :--- | | **Product Type** | Heat Sink | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | 4.37°C/W (Unducted Flow @ 200 LFM) | | **Dimensions (L x W x H)** | 40mm x 40mm x 20mm | | **Fin Configuration** | maxiFLOW (Tapered Fin Design) | | **RoHS Status** | Compliant | --- ### 2. Design and Engineering Features #### A. maxiFLOW™ Fin Geometry Unlike standard square-fin heat sinks, the maxiFLOW design features a **tapered fin** structure. This geometry increases the surface area while reducing pressure drop, allowing for more efficient heat transfer in forced-air environments. #### B. pushPIN™ Attachment System The "18B" in the part number indicates the specific mounting hardware. This system uses a flexible, spring-loaded mechanism that: * Ensures consistent pressure (clamping force) between the heat sink and the component. * Prevents damage to the PCB through controlled force application. * Simplifies installation and removal in assembly lines. #### C. Thermal Interface Material (TIM) The "R0" suffix indicates that the part typically comes with a pre-applied **Phase Change Material** or high-performance thermal pad. This ensures that there are no air gaps between the chip and the heat sink, maximizing heat conduction. --- ### 3. Decoding the Part Number The part number follows a specific nomenclature used by Advanced Thermal Solutions: | Segment | Meaning | | :--- | :--- | | **ATS** | Manufacturer (Advanced Thermal Solutions) | | **18B** | Attachment Style (pushPIN™ with specific spring/pin type) | | **93** | Design ID (Internal geometry and fin count) | | **C2** | Thermal Performance Grade / Material Coating | | **R0** | Packaging / Thermal Interface Material option | --- ### 4. Typical Applications * **Processors (CPUs/GPUs):** Cooling small-to-mid-sized processors in embedded systems. * **FPGAs & ASICs:** Managing heat in high-speed telecommunications equipment. * **Power Electronics:** Dissipating heat from power converters and motor drivers.
