The **ATS-04H-199-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 integrated circuits (ICs) and surface-mount devices. ### 1. Technical Specifications The following table summarizes the core technical parameters of this part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Thermal Resistance** | 15.83°C/W (Unducted Flow @ 100 LFM) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Spring Loaded) | | **Dimensions (L x W)** | 50.00mm x 50.00mm | | **Height (Fin Height)** | 6.00mm | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Design Features #### A. Fin Geometry This model utilizes a **Cross-Cut** fin design. Unlike straight-fin heat sinks, cross-cut fins allow for multi-directional airflow. This is critical in cramped electronic enclosures where the direction of cooling fans may not be perfectly aligned with the heat sink. #### B. Attachment Mechanism: pushPIN™ The "R0" designation indicates a specific attachment kit. * **Secure Fit:** Uses a brass or plastic push-pin with a stainless steel spring. * **Constant Pressure:** The spring ensures consistent pressure between the heat sink and the component, optimizing the effectiveness of the Thermal Interface Material (TIM). * **Vibration Resistance:** Ideal for industrial or automotive electronics where vibration might cause traditional adhesive-based sinks to fail. #### C. Thermal Interface Material (TIM) The part comes with **T766** pre-applied. This is a high-performance phase-change material or grease that fills microscopic air gaps between the CPU/GPU and the aluminum base, significantly reducing thermal impedance. --- ### 3. Performance Analysis The efficiency of the ATS-04H-199-C2-R0 is highly dependent on the Airflow Velocity (LFM - Linear Feet per Minute). * **Low Airflow (100 LFM):** High resistance (~15.83°C/W). * **High Airflow (700 LFM):** Efficiency increases significantly, dropping thermal resistance to approximately **5.00°C/W**. ### 4. Typical Applications * **Networking Equipment:** High-speed routers and switches. * **Embedded Systems:** Industrial PCs and controllers. * **Power Supplies:** Cooling MOSFETs or voltage regulators. * **FPGA/ASIC Cooling:** General-purpose cooling for medium-heat processors.
