The **ATS-08F-25-C3-R0** is a high-performance electronic 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 to prevent thermal throttling or failure. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-08F-25-C3-R0 | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Base Dimensions** | 45mm x 45mm | | **Height** | 25mm | | **Thermal Resistance** | Variable based on Airflow (LFM) | | **Fin Pattern** | Cross-Cut (Pin Fin) | --- ## 2. Key Electronic Features ### A. pushPIN™ Attachment System Unlike adhesive tapes or simple clips, the `pushPIN™` system ensures a precise and secure fit. - **Constant Pressure:** It utilizes a pre-assembled compression spring to provide uniform pressure across the component surface, maximizing heat transfer. - **Hardware:** Usually involves nylon or brass pins that lock into pre-drilled holes on the PCB. ### B. Thermal Interface Material (TIM) The "C3" in the part number indicates the type of Thermal Interface Material pre-applied to the base: - **T766 Phase Change Material:** This is a high-performance material that softens at operating temperatures to fill microscopic air gaps between the heat sink and the chip. ### C. Pin-Fin Design (Cross-Cut) Unlike standard straight-fin heat sinks, the ATS-08F series often features a **Cross-Cut** pattern. - **Omnidirectional Airflow:** This allows air to enter and exit from multiple directions, making it ideal for systems where the airflow direction is inconsistent or blocked by other components. - **Increased Surface Area:** The pin-fin geometry provides a higher surface-area-to-volume ratio compared to extruded fins. --- ## 3. Performance Breakdown Thermal performance is measured by **Thermal Resistance (°C/W)**. The lower the number, the more efficient the cooling. | Airflow Velocity (LFM) | Thermal Resistance (Unducted) | | :--- | :--- | | 200 LFM | ~6.30 °C/W | | 400 LFM | ~2.50 °C/W | | 600 LFM | ~1.80 °C/W | --- ## 4. Summary of Application This component is commonly used in: 1. **Telecommunications:** High-speed routers and switches. 2. **Embedded Systems:** Industrial PCs and automation controllers. 3. **Power Electronics:** Cooling MOSFETs or Voltage Regulator Modules (VRMs).
