The **ATS-54290D-C1-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is specifically designed as part of their "maxiFLOW™" product line to manage the thermal load of electronic components such as CPUs, GPUs, and FPGAs. --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of the part: | Characteristic | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (Black Anodized) | | **Dimensions (L x W x H)** | 42.90mm x 42.90mm x 9.50mm | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Thermal Resistance** | 3.50°C/W @ 200 LFM | | **Shape** | Square, Fin Profile | --- ### 2. Key Components & Technologies #### A. maxiFLOW™ Fin Design Unlike standard straight-fin heat sinks, the maxiFLOW™ profile features a unique flared fin geometry. This design: * Reduces air pressure drop. * Increases the surface area for heat dissipation. * Optimizes airflow in constrained spaces. #### B. maxiGRIP™ Attachment System The "C1" in the part number refers to the attachment style. This system uses a steady spring-clip mechanism that applies constant pressure to the component without requiring holes in the PCB. It consists of: 1. **Plastic Frame:** Fits around the component. 2. **Stainless Steel Spring Clip:** Snaps over the heat sink to secure it. #### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates the inclusion of a pre-applied high-performance thermal pad (often Chomerics T766 or similar). This ensures that the microscopic gaps between the chip and the heat sink are filled, minimizing thermal resistance. --- ### 3. Applications This part is commonly found in the following electronic environments: * **Networking Hardware:** High-speed routers and switches. * **Embedded Systems:** Industrial PCs and automation controllers. * **Telecommunications:** Base stations and data transmission equipment. ---
