The **ATS-05A-99-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed for cooling electronic components such as CPUs, GPUs, or power modules. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Base Dimensions** | 45mm x 45mm | | **Height (Fin)** | 20mm | | **Fin Style** | Cross-Cut (Pin Fin) | | **Thermal Resistance** | 11.51°C/W (Unducted @ 100 LFM) | --- ### 2. Key Component Features #### A. pushPIN™ Attachment Unlike adhesive-based heat sinks, this part uses the **pushPIN™** system. This involves: * **Compression Springs:** Provides precise pressure to ensure optimal thermal interface contact. * **Brass/Plastic Pins:** Secure the heat sink through pre-drilled holes in the PCB. #### B. Cross-Cut Fin Design The "99" series features a **cross-cut** fin pattern. This is superior to standard straight fins because: * It allows for multi-directional airflow (not just linear). * It increases the surface area for heat dissipation. * It creates turbulence, which helps break up the "boundary layer" of stagnant air. #### C. Thermal Performance Thermal resistance is measured in **°C/W** (Celsius per Watt). * **Low Airflow:** At 100 LFM (Linear Feet per Minute), resistance is **11.51°C/W**. * **High Airflow:** Performance improves significantly as fan speed increases (dropping to approx **2.0°C/W** at 700 LFM). --- ### 3. Application Use Cases This specific model is typically used in the following electronic environments: 1. **Telecommunications:** Cooling ASICs in networking switches. 2. **Industrial PC:** Thermal management for embedded processors. 3. **Power Supplies:** Dissipating heat from high-wattage voltage regulators. --- ### 4.
