The **ATS-08B-77-C3-R0** is a high-performance heat sink manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **maxiFLOW™** series, specifically designed for cooling electronic components like CPUs, GPUs, and FPGAs where airflow is directed through a duct or specialized housing. --- ### 1. Key Technical Specifications | Feature | Description | | :--- | :--- | | **Part Number** | ATS-08B-77-C3-R0 | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | 9.58 °C/W (at 100 LFM) | | **Fin Style** | maxiFLOW (Tapered Fin Design) | | **Dimensions** | 46.83mm x 46.83mm x 15mm | | **Compliance** | RoHS and REACH Compliant | --- ### 2. Electronic/Physical Component Breakdown #### A. The Heat Sink Body * **maxiFLOW™ Design:** Unlike standard straight-fin heat sinks, the maxiFLOW geometry features a tapered fin design. This increases the surface area for heat dissipation while minimizing the pressure drop as air passes through. * **Aluminum Construction:** Aluminum is used for its high thermal conductivity-to-weight ratio. The **Blue Anodized** finish is not just for aesthetics; it provides corrosion resistance and increases surface emissivity (improving radiative cooling). #### B. The pushPIN™ Attachment System This specific model uses a **pushPIN™** mechanism rather than adhesive or tape. * **Components:** It consists of a high-performance plastic or metal pin and a compression spring. * **Benefit:** It provides a precise "clamping force" (pressure) onto the electronic chip, ensuring the thermal interface material (TIM) is compressed perfectly for maximum heat transfer. #### C. Thermal Interface Material (TIM) * The "-R0" suffix usually indicates that the heat sink comes with a **pre-applied thermal interface material**. * This material fills the microscopic air gaps between the heat sink base and the electronic component (e.g., a power transistor or processor), significantly reducing thermal resistance. --- ### 3. Application Use Cases This part is typically found in high-reliability electronic environments such as: 1. **Telecommunications:** Cooling networking switches and routers. 2. **Industrial Controls:** Managing heat for motor controllers. 3. **Embedded Computing:** Cooling high-speed processors in tight enclosures. ---
