## Technical Overview: ATS-51450D-C2-R0 The **ATS-51450D-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "maxiFLOW™" product line, designed specifically for cooling electronic components such as BGAs (Ball Grid Arrays) and other surface-mount packages. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Heat Sink | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 45.00mm x 45.00mm x 9.50mm | | **Thermal Resistance** | 2.50 °C/W (at 200 LFM) | | **Airflow** | Straight Fin (Designed for high-speed airflow) | --- ### 2. Design and Engineering Features * **maxiFLOW™ Fin Pattern:** The tapered fin design maximizes surface area for more effective convection cooling while reducing pressure drop across the component. * **maxiGRIP™ Attachment:** This is a key electronic assembly feature. It uses a high-tension plastic frame clip and a gold-chromate-shielded brass spring-clip. This allows for: * **No Holes Required:** The clip attaches directly to the component, meaning the PCB does not need mounting holes. * **Even Pressure:** Ensures consistent contact between the heat sink and the chip for optimal heat transfer. * **Reusability:** The assembly can be removed and re-attached during testing or repair. * **Thermal Interface Material (TIM):** This part usually comes pre-applied with a high-performance thermal pad (often Phase Change Material) to bridge the microscopic gaps between the chip surface and the aluminum base. --- ### 3. Ideal Applications This specific part is used in electronics where heat dissipation is critical but vertical space is somewhat restricted (9.5mm height). Common applications include: 1. **Telecommunications:** Network switches and high-speed routers. 2. **Embedded Systems:** Industrial PCs and single-board computers. 3. **Power Electronics:** Cooling MOSFETs or Voltage Regulator Modules (VRMs). --- ### 4. Thermal Performance Data Thermal resistance indicates how effectively the part moves heat away from the electronics. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 (1.0 m/s) | 2.50 | | 300 (1.5 m/s) | 1.80 | | 400 (2.0 m/s) | 1.50 | | 500 (2.5 m/s) | 1.30 |
