The **ATS-03D-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 "pushPIN™" family, designed for cooling critical electronic components like CPUs, GPUs, and power modules. ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance (Flowing)** | 5.11 °C/W (@ 100 LFM) | | **Thermal Resistance (Static)** | 15.10 °C/W (Unducted) | | **Dimensions (L x W x H)** | 45.00mm x 45.00mm x 15.00mm | | **Fin Pattern** | Straight Fin | --- ### 2. Key Electronic & Mechanical Components The "electronic" functionality of this part refers to how it interacts with the PCB and the heat-generating semiconductors. It consists of several integrated sub-parts: #### A. The Heat Sink Body * **Material:** Extruded aluminum (6063) provides a high degree of thermal conductivity. * **Geometry:** It uses a high-density fin structure to maximize surface area for heat dissipation into the surrounding air. #### B. The pushPIN™ Attachment System Instead of using messy adhesives or simple clips, this model uses a mechanical mounting system: * **Push Pins:** Made of nylon or brass, these insert through pre-drilled holes in the PCB. * **Compression Springs:** These ensure a consistent, pre-determined "Pressure" is applied to the electronic component, optimizing the thermal interface. #### C. Thermal Interface Material (TIM) * **Pre-Applied Material:** This model usually comes with **T766** thermal phase-change material or grease pre-applied to the base. * **Function:** It fills microscopic air gaps between the semiconductor die and the heat sink base to ensure maximum heat transfer. --- ### 3. Application Use Cases This specific part is typically used in the following electronic environments: 1. **Telecommunications:** Cooling high-speed processors in routers and switches. 2. **Embedded Systems:** For industrial PCs where vertical space is limited (15mm height). 3. **Power Electronics:** Dissipating heat from MOSFETs or IGBTs in power conversion circuits. ---
