The **ATS-55210K-C2-R0** is a high-performance thermal management component, specifically an **Advanced Thermal Solutions (ATS) BGA (Ball Grid Array) Heat Sink**. It belongs to the *maxiFLOW™* product line, designed for cooling electronic integrated circuits (ICs). --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-55210K-C2-R0 | | **Type** | BGA Heat Sink (maxiFLOW™) | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Material** | Black Anodized Aluminum | | **Dimensions (L x W)** | 21mm x 21mm | | **Height** | 14.5mm | | **Thermal Resistance** | 5.8 °C/W (at 200 LFM) | | **Compliance** | RoHS Compliant | --- ### 2. Key Electronic & Mechanical Components #### A. The Fin Design (maxiFLOW™) Unlike traditional straight-fin heat sinks, this part uses a **flared fin geometry**. This design maximizes the surface area for convective heat transfer while increasing air turbulence. This is critical for high-density electronic assemblies where space is limited but heat dissipation requirements are high. #### B. The maxiGRIP™ Attachment The "K" in the part number often refers to the assembly kit which includes: * **Plastic Frame Clip:** A high-strength clip that snaps around the perimeter of the electronic component. * **SteadyDrive™ Spring Clip:** A gold-colored metal spring clip that applies constant, even pressure across the interface. * **Benefits:** This mechanical attachment avoids the need for drilling holes in the PCB and allows for easy removal/rework. #### C. Thermal Interface Material (TIM) The "C2" designation typically indicates that the heat sink comes pre-applied with a **Thermal Interface Material**. * **Purpose:** It fills the microscopic air gaps between the CPU/GPU die and the aluminum heat sink base to ensure efficient heat conduction. --- ### 3. Application Use Cases This part is commonly found in the following electronic environments: 1. **Telecommunications:** Cooling FPGA and ASIC chips in routers and switches. 2. **Embedded Systems:** High-performance industrial controllers. 3. **Video Processing:** DSPs and high-speed processors used in image rendering. ---
