The part number **ATS-12F-77-C3-R0** refers to a high-performance **heat sink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push-pin" series designed for cooling electronic components like CPUs, GPUs, or high-power ASICs. --- ### 1. Technical Specifications The part number is an alphanumeric code that describes the specific physical properties of the component: | Feature | Specification | | :--- | :--- | | **Series** | pushPIN™ Heat Sink | | **Fin Type** | Fine Pitch (Straight Fin) | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | Push-Pin (Spring-loaded) | | **Thermal Resistance** | ~9.42°C/W (Unducted Flow @ 100 LFM) | | **Dimensions (L x W)** | 25.00 mm x 25.00 mm | | **Height** | 30.00 mm | --- ### 2. Breakdown of the Part Number Understanding the nomenclature helps in identifying its compatibility: * **ATS**: Manufacturer (Advanced Thermal Solutions). * **12**: Internal series identification. * **F**: Fine pitch fin pattern (optimized for airflow). * **77**: Specific dimension code (25mm x 25mm footprint). * **C3**: Thermal Interface Material (TIM) and finish code (usually indicates a high-performance thermal pad/grease is pre-applied). * **R0**: RoHS compliant version. --- ### 3. Key Electronic Functions While a heat sink is a mechanical part, it is critical for the "Electronic Health" of a circuit: 1. **Thermal Management**: It prevents **Thermal Throttling**, where a processor slows down its clock speed to reduce heat, ensuring consistent performance. 2. **Component Longevity**: By maintaining a lower junction temperature, it prevents the degradation of semiconductor materials (Arrhenius Equation), extending the Mean Time Between Failures (MTBF). 3. **Mechanical Security**: The "push-pin" design uses a brass or plastic pin with a spring to provide constant downward pressure, ensuring a perfect "wetting" of the thermal interface material between the chip and the aluminum. --- ### 4. Mounting & Installation The heat sink requires specific PCB holes for installation: * **Pitch (Hole-to-Hole):** Approximately 30.00 mm. * **Hardware:** Includes a flexible "push-pin" system that allows for tool-free assembly and prevents over-tightening which could crack a silicon die.
