The **ATS-05H-129-C2-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 hardware failure. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | push-PIN™ | | **Fin Type** | XCUT (Straight Fins with cross-cuts) | | **Dimensions** | 54mm x 54mm x 20mm | | **Thermal Resistance** | 8.68°C/W (Unducted Flow @ 100 LFM) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Components & Design Features #### A. push-PIN™ Attachment Unlike adhesive-based heat sinks, this model uses a **push-pin and spring mechanism**. This provides several advantages: * **Constant Pressure:** The springs ensure uniform contact between the heat sink and the component, optimizing heat transfer. * **Reliability:** It is more vibration-resistant than thermal tape. * **Repairability:** The heat sink can be removed and reinstalled without damaging the PCB (Printed Circuit Board). #### B. XCUT Fin Design The "XCUT" geometry refers to straight fins that have been cut cross-wise. This design: * Increases surface area for convection. * Allows air to flow from multiple directions (omni-directional), making it ideal for systems where the airflow path is not perfectly straight. #### C. Thermal Interface Material (TIM) The unit comes with **T766** pre-applied. This is a high-performance thermal pad that fills microscopic air gaps between the component die and the aluminum base, significantly reducing thermal impedance. --- ### 3. Thermal Performance Data Performance varies based on the airflow (measured in Linear Feet per Minute - LFM) provided by system fans: | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 8.68 | | 300 (1.5 m/s) | 1.59 | | 500 (2.5 m/s) | 1.14 | | 700 (3.5 m/s) | 0.94 | --- ### 4. Application Use Cases * **Embedded Systems:** Cooling processors in industrial computers. * **Telecommunications:** Dissipating heat from high-speed networking chips. * **Power Electronics:** Managing heat for large MOSFET arrays or voltage regulators.
