The **ATS-11D-93-C2-R0** is a high-performance thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal properties: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ HS Assembly | | **Attachment Method** | Push-Pin (Spring Loaded) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance** | 12.32°C/W (Unducted) | | **Airflow Pattern** | Straight Fin | --- ### 2. Physical Dimensions Precision measurements are critical for PCB clearance and component fitment: * **Size (L x W):** 40mm x 40mm * **Height:** 20mm (measured from the base to the top of the fins) * **Pitch:** The distance between holes is designed for specific board layouts. --- ### 3. Key Electronic Functions While the heat sink itself is a passive mechanical part, its role in an electronic circuit is vital for operational stability: 1. **Thermal Dissipation:** It increases the surface area of the heat-generating component, allowing air (convection) to carry heat away more efficiently. 2. **Protection:** By maintaining a lower junction temperature ($T_j$), it prevents **thermal throttling** and extends the lifespan of the semiconductor. 3. **Mechanical Stability:** The "push-pin" system uses a precise spring-loaded mechanism to ensure uniform pressure across the component surface, which optimizes the interface with Thermal Interface Material (TIM). --- ### 4. Component Components The assembly usually consists of: * **The Heat Sink:** The aluminum finned body. * **Push-Pins:** Usually made of brass or plastic to secure the unit to the PCB. * **Springs:** Provides the necessary downward force. * **TIM (Thermal Interface Material):** Often pre-applied to the base to fill microscopic air gaps between the heat sink and the chip.
