The **ATS-15D-75-C3-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™" series, designed for precision cooling of electronic integrated circuits (ICs) and surface-mount devices. --- ### 1. Technical Specifications | Parameter | Specification | Details | | :--- | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions | ATS | | **Material** | Aluminum | Lightweight with high thermal conductivity | | **Finish** | Blue Anodized | Increases surface emissivity and prevents corrosion | | **Thermal Resistance** | 1.57 °C/W (@ 100 LFM) | Efficiency at low airflow | | **Dimensions (L x W)** | 45mm x 45mm | Standard square footprint | | **Height** | 30.00mm | Vertical clearance requirement | | **Attachment Type** | pushPIN™ | Spring-loaded pin mechanism | --- ### 2. Design and Construction #### **Fin Profile: Cross-Cut** The part features a **straight fin, cross-cut** design. This creates a grid of pins rather than long continuous walls, allowing for: * **Omnidirectional Airflow:** Air can enter the heat sink from any direction, making it ideal for systems where the airflow path is not strictly linear. * **Turbulence Generation:** The gaps between pins break up the boundary layer of air, increasing heat transfer efficiency. #### **Attachment Mechanism (pushPIN™)** Unlike adhesive tapes or simple clips, the `75` series uses a push-pin system with a built-in spring: * **Constant Pressure:** Ensures consistent contact between the heat sink base and the electronic component. * **Secure Fit:** Prevents the heat sink from shifting due to mechanical shock or vibration. --- ### 3. Thermal Performance Metrics Thermal resistance indicates how many degrees Celsius the component temperature will rise per Watt of power dissipated. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 1.57 | | 300 (1.5 m/s) | 0.82 | | 500 (2.5 m/s) | 0.67 | --- ### 4. Part Number Breakdown * **ATS**: Manufacturer (Advanced Thermal Solutions). * **15D**: Series identifier. * **75**: Push-pin pitch and style. * **C3**: Thermal Interface Material (TIM). This usually indicates it comes with a pre-applied high-performance phase-change material or grease. * **R0**: RoHS Compliant / Revision code. ---
