Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Dimensions** | 19.0mm x 19.0mm x 14.5mm (L x W x H) | | **Material** | Aluminum (Black Anodized) | | **Thermal Resistance** | 5.80°C/W @ 200 LFM (Linear Feet per Minute) | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Interface Material** | T766 (Thermal Tape/Pad) | --- ### 2. Component Design & Anatomy #### A. Fin Geometry The part utilizes **spread-fin technology**. Unlike standard straight fins, these fins are flared outward. This design increases the surface area and encourages air turbulence, which significantly improves heat dissipation in constrained spaces where airflow might be limited. #### B. Attachment Mechanism (maxiGRIP™) The "K" in the part number often refers to the specific attachment kit. The **maxiGRIP™** system consists of: 1. **Plastic Frame Clip:** A high-temperature plastic frame that snaps around the component. 2. **Stainless Steel Spring Clip:** A "steady spring" that applies constant, even pressure across the center of the heat sink to the component, ensuring optimal thermal contact. #### C. Thermal Interface Material (TIM) The unit comes pre-applied with **T766**, a high-performance phase-change material or thermal tape. This eliminates the need for manual application of thermal grease and ensures a consistent bond between the chip and the heat sink. --- ### 3. Usage & Applications This heat sink is typically used for cooling **BGA (Ball Grid Array)** components. Common applications include: * **Networking Hardware:** Switches, routers, and high-speed modems. * **Embedded Systems:** Industrial controllers and IoT gateways. * **Telecommunications:** Optical modules and base station electronics. --- ### 4.
