The **ATS-05F-77-C2-R0** is a specific part number for 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 BGA (Ball Grid Array) chips, CPUs, or GPUs. --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of this component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 25mm x 25mm (Base) x 20mm (Height) | | **Attachment Method** | Push Pin (Plastic) with Springs | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 9.30 °C/W @ 1.0 m/s (LFM) | | **Compliance** | RoHS Compliant | --- ### 2. Breakdown of the Part Number The part number follows a specific nomenclature used by ATS to identify the cooling capability and mounting hardware: * **ATS**: Manufacturer (Advanced Thermal Solutions). * **05**: Refers to the specific series/mounting hole pattern. * **F**: Indicates the fin density or specific thermal profile. * **77**: Designates the physical height and configuration. * **C2**: Refers to the **Thermal Interface Material (TIM)**; in this case, it usually signifies that **T766** phase-change material or a specific thermal tape is pre-applied. * **R0**: Revision number. --- ### 3. Key Electronic Functions While the heat sink itself is passive (it does not consume electricity), it plays a critical role in the reliability of electronic circuits: * **Thermal Management:** It increases the surface area of the heat-generating component, allowing for faster heat dissipation into the surrounding air via convection. * **Overheating Prevention:** By keeping the junction temperature ($T_j$) of a semiconductor below its maximum limit, it prevents thermal throttling and permanent hardware damage. * **Structural Integrity:** The push-pin mounting system provides a consistent downward force (pressure), ensuring that the thermal interface material fills all microscopic gaps between the chip and the heat sink. --- ### 4. Typical Applications * **Embedded Systems:** Cooling microcontrollers or small processors. * **Networking Gear:** Used on switches or routers for ASIC cooling. * **Power Supplies:** Dissipating heat from voltage regulators or MOSFETs. ---
