The **ATS-21B-72-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "maxiFLOW™" series, designed for high-density cooling requirements in electronic systems. --- ### ## Technical Specifications The following table outlines the physical and thermal characteristics of the part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Base Material** | Aluminum (typically AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Thermal Resistance** | 5.10°C/W @ 100 LFM (Linear Feet per Minute) | | **Dimensions (L x W x H)** | 45.00mm x 45.00mm x 25.00mm | | **Fin Style** | Straight Fin | | **Weight** | ~40-60 grams (varies by specific pin config) | --- ### ## Key Electronic & Mechanical Components ### 1. The Fin Structure (maxiFLOW™) Unlike standard extruded heat sinks, the ATS-21B-72-C2-R0 features a tapered fin design. This geometry maximizes the surface area for heat dissipation while minimizing the pressure drop as air passes through, which is critical for sensitive PCB components like CPUs, FPGAs, or GPUs. ### 2. pushPIN™ Attachment System The "R0" suffix often indicates the attachment hardware. This part uses a **pushPIN™** system: * **Springs:** Provides a precise amount of downward pressure (compression force) to ensure optimal contact with the electronic component. * **Pins:** Usually made of brass or plastic, designed to snap into pre-drilled holes in the PCB. ### 3. Thermal Interface Material (TIM) Most "C2" variants come pre-applied with a high-performance **Thermal Interface Material**. This is the chemical layer between the electronic chip and the heat sink base that eliminates air gaps to improve heat transfer. --- ### ## Application Use Cases This specific part is used in environments where electronic components generate significant heat but have limited space: * **Networking:** Routers, switches, and high-speed modems. * **Embedded Systems:** Industrial PC boards and controllers. * **Power Supplies:** Cooling MOSFETs or power transistors. ---
