The **ATS-19F-51-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power transistors. ### 1. Technical Specifications The following table summarizes the key electronic and mechanical properties of the part: | Specification | Details | | :--- | :--- | | **Part Number** | ATS-19F-51-C2-R0 | | **Product Type** | Heat Sink (Passive Cooling) | | **Fin Style** | Straight Fin | | **Material** | Aluminum (Blue Anodized) | | **Thermal Resistance** | 6.62° C/W @ 100 LFM | | **Dimensions (L x W x H)** | 40mm x 40mm x 20mm | | **Attachment Method** | pushPIN™ | | **Interface Material** | T766 (Thermal Interface Material pre-applied) | --- ### 2. Electronic Application & Functionality While a heat sink is a mechanical part, its role in an electronic circuit is critical for **Thermal Stability**: * **Thermal Dissipation:** It increases the surface area of a heat-generating semiconductor, allowing for efficient heat transfer to the surrounding air. * **Thermal Interface Material (TIM):** The "C2" in the part number indicates a specific thermal interface (T766), which fills microscopic air gaps between the electronic component and the heat sink, reducing thermal impedance. * **Protection:** By maintaining the junction temperature ($T_j$) of electronic components within safe operating limits, it prevents **Thermal Throttling** and **Permanent Failure**. --- ### 3. Attachment Mechanism: pushPIN™ This specific part utilizes the ATS **pushPIN™** system, which is crucial for PCB (Printed Circuit Board) design: 1. **Spring-Loaded:** Provides consistent pressure to ensure optimal contact with the electronic component. 2. **Hardware:** Includes a brass or plastic pin with a stainless steel spring. 3. **Compatibility:** Requires pre-drilled holes in the PCB at specific intervals (usually according to the 40mm footprint). --- ### 4. Airflow Performance Data Performance varies based on the airflow (Velocity) within the electronic enclosure: | Air Velocity (LFM) | 100 | 300 | 500 | 700 | | :--- | :--- | :--- | :--- | :--- | | **Thermal Resistance (°C/W)** | 6.62 | 2.36 | 1.64 | 1.34 |
