The **ATS-54375W-C2-R0** is a high-performance thermal management component manufactured by **Advanced Thermal Solutions (ATS)**. Specifically, it belongs to the **maxiFLOW™** series of heat sinks, designed for cooling electronic components such as processors, FPGAs, and ASICs. --- ### 1. Technical Specifications The following table outlines the key physical and thermal properties of the part: | Parameter | Specification | | :--- | :--- | | **Component Type** | Heat Sink | | **Series** | maxiFLOW™ | | **Dimensions (L x W x H)** | 37.00mm x 37.00mm x 24.50mm | | **Material** | Aluminum | | **Finish** | Black Anodized | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Thermal Resistance** | 1.80°C/W (at 200 LFM) | --- ### 2. Key Design Features #### A. maxiFLOW™ Fin Geometry The "W" in the part number often refers to the **spread fin geometry**. Unlike standard straight fins, these fins are tapered and flared. This design: * Increases the surface area for heat dissipation. * Reduces pressure drop, allowing air to flow more easily through the sink. * Is optimized for high-velocity airflow environments. #### B. maxiGRIP™ Attachment System This part utilizes a specialized mechanical attachment system rather than thermal adhesive or push-pins. * **Plastic Frame Clip:** A frame snaps around the component. * **Stainless Steel Spring Clip:** A "steady-force" spring applies consistent pressure across the interface. * **Reliability:** This system allows the heat sink to be removed and reattached without damaging the PCB, which is critical during testing or rework. #### C. Thermal Interface Material (TIM) The "C2" designation typically indicates that the part comes pre-applied with a **Thermal Interface Material**. Specifically: * **Type:** Often high-performance phase-change material or thermal pad. * **Purpose:** To eliminate air gaps between the component die and the heat sink base, ensuring maximum heat transfer. --- ### 3. Application Use Cases This specific heat sink is used in dense electronic environments where vertical space is available (24.5mm height) but board real estate is limited. Common applications include: * **Telecommunications:** Network switches and routers. * **Computing:** High-speed servers and data storage units. * **Industrial Power:** Power supplies and motor controllers. ---
