Technical Specifications The following table outlines the physical and thermal properties of this specific component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push Pin (Plastic/Brass) | | **Dimensions (L x W x H)** | 25.0mm x 25.0mm x 15.0mm | | **Thermal Resistance** | ~12.23° C/W @ 100 LFM (Airflow) | | **Thermal Interface Material** | T412 (Pre-applied) | --- ### 2. Key Components & Design Features #### A. Heat Sink Geometry * **Fin Style:** Straight-fin design. This is optimized for unidirectional airflow (forced convection), typically provided by a system fan. * **Form Factor:** A compact $25 \times 25$ mm footprint makes it ideal for small PCB areas where space is at a premium. #### B. Attachment Mechanism (Push Pin) The "01F" in the part number indicates a specific push-pin and spring assembly: * **Components:** Plastic or brass pins combined with compression springs. * **Benefit:** Provides consistent pressure on the component, improving thermal contact while allowing for easy installation and removal without messy adhesives. #### C. Thermal Interface Material (TIM) The unit comes with **T412** pre-applied to the base. * **Function:** It fills microscopic air gaps between the heat sink and the chip to maximize heat transfer. * **Efficiency:** T412 is a high-performance material that balances thermal conductivity with electrical insulation. --- ### 3. Thermal Performance Analysis The efficiency of the ATS-01F-138-C3-R0 is highly dependent on airflow (LFM - Linear Feet per Minute). | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (Natural-ish) | 12.23 | | 300 (Moderate Fan) | 6.80 | | 500 (High Flow) | 5.20 | --- ### 4. Part Number Breakdown Understanding the nomenclature helps in identifying variations: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **01F:** Specific push-pin and spring configuration. * **138:** Unique geometry/fin height identifier. * **C3:** Material/Finish code (Blue Anodized). * **R0:** Revision or RoHS compliance status.
