The **ATS-05B-181-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) Heat Sink** designed for cooling electronic integrated circuits (ICs) and other surface-mount components. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by Advanced Thermal Solutions. Here are the core specifications: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Plastic Pins / Springs) | | **Thermal Resistance** | 11.95°C/W (Unducted Flow @ 100 LFM) | | **Dimensions (L x W)** | 40mm x 40mm | | **Height** | 10mm | | **Pitch** | Fine Pitch (High fin density) | --- ### 2. Component Breakdown The assembly consists of four primary electronic/mechanical sub-parts: #### A. The Heat Sink Body Manufactured from high-grade aluminum. The **C2** in the part number indicates a specific thermal interface material (TIM) or finish, and the **R0** indicates the revision level. The fine-fin design maximizes surface area for convective cooling. #### B. The pushPIN™ Attachment System Instead of using messy adhesives or permanent solder, this part uses a mechanical "pushPIN" system. * **Benefits:** Provides consistent pressure for optimal thermal contact. * **Components:** Plastic pins and stainless steel springs. #### C. Thermal Interface Material (TIM) The bottom of the heat sink usually comes pre-applied with a thermal pad or phase-change material. This fills the microscopic air gaps between the heat sink and the electronic chip (CPU, GPU, or FPGA), significantly lowering thermal resistance. #### D. Blue Anodized Coating The blue color is not just aesthetic; the anodization process provides: * Increased corrosion resistance. * Electrical insulation (to prevent shorting if it touches nearby components). * Improved emissivity for radiant heat transfer. --- ### 3. Common Applications This part is typically found in the following electronic environments: * **Telecommunications:** Cooling network switches and routers. * **Industrial PC:** Cooling processors in fanless or low-airflow enclosures. * **Embedded Systems:** For high-heat ARM or FPGA chips. ---
