The **ATS-08B-81-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is a critical passive cooling component used in electronic systems to dissipate heat from integrated circuits (ICs), such as CPUs, GPUs, or power transistors. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Property | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Base Material** | Aluminum | | **Finish** | Blue Anodized | | **Fin Type** | Straight Fin | | **Attachment Method** | Push-Pin | | **Dimensions (L x W x H)** | 30.00mm x 30.00mm x 10.00mm | | **Thermal Resistance** | 14.03 °C/W (@ 100 LFM) | --- ### 2. Key Electronic Features #### A. Thermal Management As electronic components operate, they generate heat due to internal resistance. The **ATS-08B-81-C2-R0** increases the surface area available for heat exchange. * **Convection:** It relies on airflow (natural or forced) to carry heat away from the fins. * **Thermal Interface Material (TIM):** This specific model typically comes with **T766** pre-applied, which is a high-quality thermal phase-change material that ensures minimal thermal resistance between the heat source and the aluminum base. #### B. Mechanical Attachment (Push-Pin) Unlike adhesive-based heat sinks, this part uses a **brass push-pin** mechanism with a compression spring. * **Reliability:** It provides consistent pressure across the surface of the component. * **Serviceability:** It can be removed and re-installed more easily than epoxy-bonded solutions. * **Vibration Resistance:** The spring-loaded design makes it suitable for industrial or automotive applications where mechanical shock is a factor. #### C. Material and Coating * **Aluminum 6063:** Chosen for its high thermal conductivity and lightweight properties. * **Anodization:** The blue anodized finish is not just for aesthetics; it provides corrosion resistance and increases surface emissivity (radiative heat transfer). --- ### 3. Application Use-Cases This specific size (30mm x 30mm) is commonly found in: 1. **Network Switches:** Cooling ASICs and processing chips. 2. **Embedded Systems:** Industrial PCs where space is limited but heat density is high. 3. **Power Supplies:** Cooling voltage regulators (VRMs). ---
