The **ATS-20D-86-C2-R0** is a specific high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It belongs to their *maxiFLOW™* product line, designed to provide high thermal performance with low pressure drop. Below is a breakdown of its technical specifications and electronic application characteristics. --- ### 1. General Specifications This part is a thermal management component used to dissipate heat from electronic integrated circuits (ICs) like CPUs, FPGAs, and GPUs. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Material** | Aluminum (with Blue Anodized finish) | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Thermal Resistance** | 2.50°C/W (at 200 LFM) | --- ### 2. Physical Dimensions Precision in dimensions is critical for PCB layout and ensuring the heat sink does not interfere with neighboring components. | Dimension | Value (mm) | Value (inches) | | :--- | :--- | :--- | | **Length** | 45.00 mm | 1.77" | | **Width** | 40.00 mm | 1.57" | | **Height (Fin)** | 25.00 mm | 0.98" | | **Pitch (Mounting)** | 38.00 mm | 1.50" | --- ### 3. Key Electronic/Thermal Features * **maxiFLOW™ Design:** The fin structure features a flared design. This increases the surface area for radiation and convection while allowing air to flow through more easily than traditional straight-fin heat sinks. * **pushPIN™ Attachment:** The "R0" suffix indicates the mounting system. It uses a flexible, spring-loaded pin mechanism that provides a consistent pressure (TIM - Thermal Interface Material) against the chip, ensuring optimal heat transfer without cracking the silicon die. * **Blue Anodized Finish:** The blue coating is not just aesthetic; it provides increased corrosion resistance and slightly improves the emissivity for radiant cooling. --- ### 4. Thermal Performance Data Performance varies based on the airflow (Linear Feet per Minute - LFM) within the electronics enclosure: * **Unducted Flow (200 LFM):** 2.50°C/W * **Unducted Flow (400 LFM):** 1.40°C/W * **Unducted Flow (600 LFM):** 1.10°C/W --- ### 5. Part Number Decoder Understanding the code helps in selecting alternates: * **ATS:** Manufacturer prefix. * **20D:** Series/Mounting style. * **86:** Specific dimensions and fin configuration. * **C2:** Material/Finish (Aluminum, Blue Anodized). * **R0:** Packaging/Revision code.
