The **ATS-51290D-C1-R0** is a high-performance electronic thermal management component, specifically a **heat sink** designed by Advanced Thermal Solutions (ATS). It is part of the "maxiFLOW™" series, engineered for high-density electronic packaging where airflow is critical. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Black Anodized) | | **Attachment Method** | maxiGRIP™ (Plastic Frame Clip) | | **Dimensions (L x W)** | 29.00 mm x 29.00 mm | | **Height** | 9.50 mm | | **Thermal Resistance** | 6.40° C/W (@ 200 LFM) | | **Interface Material** | T766 (Phase Change Material) | --- ### 2. Key Electronic Components & Technologies #### A. maxiFLOW™ Fin Design Unlike standard square-cut heat sinks, the ATS-51290D-C1-R0 features a tapered fin geometry. This design reduces pressure drop and increases the surface area exposed to airflow, which is critical for cooling power-hungry ICs (Integrated Circuits) like FPGAs and processors. #### B. maxiGRIP™ Attachment System This part uses a unique mechanical attachment system rather than traditional adhesive tapes or screws: * **Plastic Frame Clip:** A frame that snaps onto the perimeter of the component. * **Steady Spring:** A stainless steel "X" spring that applies constant pressure to the center of the heat sink. * **Purpose:** Ensures consistent contact with the electronic chip, facilitating better heat transfer while allowing the heat sink to be removed or re-attached without damaging the PCB. #### C. Thermal Interface Material (TIM) The part comes pre-applied with **T766**. In electronics, the TIM is crucial because it fills microscopic air gaps between the semiconductor die and the heat sink base. T766 is a phase-change material that offers low thermal impedance. --- ### 3. Application Use Cases This specific part is typically found in the following electronic environments: 1. **Telecommunications:** Cooling networking chips in switches and routers. 2. **Embedded Systems:** High-performance computing modules where vertical space is limited (only 9.5mm height). 3. **Power Electronics:** Dissipating heat from VRMs (Voltage Regulator Modules). ---
