The **ATS-12G-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 "push pin" attachment series designed for cooling integrated circuits (ICs) like CPUs, GPUs, or FPGAs. --- ## 1. Technical Specifications Below are the primary physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Brass) with Compression Spring | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 5.11°C/W (at 200 LFM) | | **Dimensions (L x W x H)** | 45mm x 45mm x 25mm | | **Spring Type** | ATS-HK127-R0 | --- ## 2. Key Components & Design Features ### A. Fin Geometry (Straight Fin) The "Straight Fin" design is optimized for **forced-air cooling**. It allows air from a system fan to pass through the channels with minimal pressure drop, effectively stripping heat away from the aluminum surfaces. ### B. Push-Pin Attachment Mechanism Instead of using messy thermal adhesives or tapes, this part uses a mechanical push-pin system: * **Stability:** Provides consistent pressure across the interface for better thermal transfer. * **Reliability:** The brass push-pins and steel springs ensure the heat sink stays mounted even during high-vibration or shock events. * **Pre-Drilled Holes:** Requires specific hole patterns on the PCB for installation. ### C. Thermal Interface Material (TIM) Most "R0" variants come with a **pre-applied phase-change material** or thermal pad on the base. This fills the microscopic air gaps between the component and the heat sink base, significantly lowering thermal resistance. --- ## 3. Application Use Cases The ATS-12G-72-C2-R0 is typically used in the following environments: 1. **Telecommunications:** Cooling high-speed processors in routers and switches. 2. **Embedded Systems:** Industrial PCs where mechanical shock might dislodge adhesive-mounted sinks. 3. **Power Supplies:** Managing heat for high-output MOSFETs or voltage regulators. --- ## 4. Performance at Airflow Thermal resistance varies based on the Linear Feet per Minute (LFM) of airflow: * **@ 200 LFM:** 5.11°C/W * **@ 400 LFM:** 3.10°C/W * **@ 600 LFM:** 2.50°C/W
