The **ATS-55375K-C1-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their **maxiFLOW™** product line, specifically designed for cooling high-power electronic components like BGA (Ball Grid Array) packages. --- ## 1. Technical Specifications Below is a breakdown of the physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Black Anodized) | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Dimensions (L x W x H)** | 37.6 x 37.6 x 14.5 mm | | **Thermal Resistance** | 3.30 °C/W (at 200 LFM) | | **Flow Pattern** | High Performance Tapered Fin | | **RoHS Status** | Compliant | --- ## 2. Key Electronic & Mechanical Features ### A. The maxiFLOW™ Fin Design Unlike standard straight-fin heat sinks, the ATS-55375K-C1-R0 utilizes a tapered, high-aspect-ratio fin design. This increases the surface area for heat dissipation while minimizing pressure drop, allowing the electronic component to stay cool even in restricted airflow environments. ### B. maxiGRIP™ Attachment One of the critical "electronic" design features is the attachment mechanism. - **No Holes Required:** It uses a plastic frame clip and a stainless steel spring clip. - **Stress Protection:** The frame clip attaches to the component without needing holes in the PCB, preventing mechanical stress on the solder balls of the BGA package. - **Reusability:** The assembly can be easily removed for maintenance or testing. ### C. Thermal Interface Material (TIM) The "R0" at the end of the part number typically indicates that the unit comes pre-applied with a **Thermal Interface Material**. In this case, it usually features **Chomerics T766**, a high-performance phase-change material that fills microscopic air gaps between the heat sink and the chip to maximize heat transfer. --- ## 3. Typical Applications This heat sink is commonly used for cooling the following electronic components: 1. **FPGA/ASIC:** High-speed processors in telecommunications. 2. **Processors:** Embedded CPUs in industrial computing. 3. **Network Switches:** Components requiring low-profile cooling in rack-mounted hardware. ---
