The **ATS-54375D-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "superGRIP" series, designed specifically for cooling electronic components such as BGAs (Ball Grid Arrays) and processors. --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of the part: | Characteristic | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | superGRIP™ | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 42.5mm x 42.5mm x 9.5mm | | **Thermal Resistance** | 6.8°C/W (at 200 LFM) | | **Attachment Method** | superGRIP™ (Clip-on) | | **Shape** | Square, Fine Fin | --- ### 2. Key Components & Design Features #### A. The Fin Profile The heat sink uses a **straight-fin** design. This allows for high-density surface area contact with the air. The "D" in the part number often signifies a specific fin density or height profile optimized for forced-air cooling (fans) rather than natural convection. #### B. The superGRIP™ Attachment One of the most critical electronic "parts" of this assembly isn't the metal itself, but the mounting mechanism: * **Plastic Frame:** A high-temperature plastic frame clips around the electronic component (BGA). * **Metal Clip:** A stainless steel "spring clip" passes through the heat sink fins and snaps into the frame. * **No Holes Required:** Unlike traditional heat sinks, this does not require holes in the Printed Circuit Board (PCB), preserving space for electrical traces. #### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates that the part comes with a pre-applied **Thermal Interface Material**. This is a phase-change material or a high-conductivity pad that fills microscopic air gaps between the chip surface and the heat sink base to maximize heat transfer. --- ### 3. Application Use Cases This part is commonly found in the following electronic assemblies: 1. **Telecommunications:** High-speed routers and switches. 2. **Embedded Systems:** Industrial PCs where vibration resistance is necessary. 3. **Power Supplies:** Cooling voltage regulators or power ICs. ---
