The **ATS-20H-75-C3-R0** is a high-performance electronic thermal management component, specifically a **push-pin heat sink** manufactured by Advanced Thermal Solutions (ATS). --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Parameter | Specification | | :--- | :--- | | **Component Type** | Heat Sink | | **Attachment Method** | Push-Pin (Plastic or Brass) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 25.0mm x 25.0mm x 20.0mm | | **Fin Style** | Straight Fin | | **Thermal Resistance** | Approx. 4.90 °C/W @ 200 LFM | | **Compression Spring** | Pre-assembled | --- ## 2. Key Electronic Features ### A. Material & Surface Treatment The unit is made from high-grade aluminum. The **Blue Anodized** finish is not just for aesthetics; it provides: * **Corrosion Resistance:** Protects the aluminum from oxidation. * **Improved Emissivity:** Enhances the radiation component of heat transfer. * **Electrical Insulation:** Anodization creates a non-conductive layer on the surface. ### B. Thermal Performance This heat sink is designed for **Forced Airflow (LFM)** environments. The straight-fin design allows for low pressure drop, making it efficient for cooling high-speed chips such as: * BGA (Ball Grid Array) processors. * FPGAs (Field Programmable Gate Arrays). * High-speed power MOSFETs. ### C. Mechanical Mounting (Push-Pin) Unlike adhesive-based heat sinks, the `ATS-20H-75-C3-R0` uses a mechanical push-pin system. * **Consistent Pressure:** The built-in spring ensures a specific amount of downward force (pressure) on the thermal interface material (TIM). * **Reliability:** Mechanical pins are more resistant to shock and vibration than thermal tape or epoxy. --- ## 3.
