## Technical Overview of ATS-55210D-C1-R0 The **ATS-55210D-C1-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It belongs to the **maxiFLOW™** series, which is designed specifically for cooling electronic components such as processors, FPGAs, and ASICs in constrained airflow environments. ### 1. Key Specifications The following table outlines the physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Dimensions (L x W x H)** | 55mm x 55mm x 10mm | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | maxiGRIP™ (Steady spring clip) | | **Thermal Resistance** | 2.50 °C/W (at 200 LFM) | | **RoHS Status** | Compliant | --- ### 2. Design and Engineering Features * **maxiFLOW™ Fin Geometry:** The fins are designed with a tapered, high-aspect-ratio profile. This geometry increases the surface area while reducing pressure drop, making it highly efficient for forced-convection cooling. * **maxiGRIP™ Attachment:** One of the most critical "electronic part" interfaces is the mounting system. It uses a plastic frame clip (pedestal) and a stainless steel "X" spring clip. This provides: * **Uniform Pressure:** Ensures consistent thermal interface material (TIM) contact. * **Easy Rework:** Allows the heat sink to be removed and reattached without damaging the PCB. * **No Holes Required:** It clips directly to the component, saving PCB real estate. * **Thermal Interface Material (TIM):** This part usually comes pre-applied with **Chomerics T766**, a high-performance phase-change material that fills microscopic air gaps between the component and the heat sink. --- ### 3. Application Use Cases The ATS-55210D-C1-R0 is typically used in the following electronic sectors: 1. **Telecommunications:** High-speed routers and switches where airflow is directional. 2. **Computing:** Server blades and industrial embedded systems. 3. **Power Electronics:** Cooling for large MOSFET arrays or power modules. --- ### 4.
