The **ATS-04H-199-C3-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 power transistors to prevent thermal throttling or hardware failure. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this part: | Characteristic | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Base Dimensions** | 50mm x 50mm | | **Height (Profile)** | 6mm | | **Thermal Resistance** | 15.91°C/W (at 100 LFM) | | **Airflow Path** | Horizontal (Straight Fin) | --- ### 2. Key Design Elements #### A. Fin Profile (Straight Fin) The "Straight Fin" design is optimized for high-airflow environments. Because the height is very low (6mm), it is ideal for **low-profile applications** (like 1U servers or slim embedded systems) where vertical space is constrained. #### B. pushPIN™ Attachment Unlike adhesive tapes that can degrade over time, the `pushPIN™` mechanism ensures: * **Constant Pressure:** A brass or plastic pin with a compressed spring provides consistent contact between the heat sink and the component. * **Secure Mounting:** It utilizes pre-drilled holes in the PCB to ensure the heat sink does not shift during vibration or shipping. #### C. Thermal Interface Material (TIM) The "C3" in the part number indicates that it typically comes with **T766** thermal phase-change material or a high-performance grease pre-applied to the base. This fills microscopic air gaps between the component and the heat sink to improve heat transfer. --- ### 3. Electronic Application Scenarios This part is commonly used in the following electronic setups: * **Network Switches/Routers:** Cooling ASICs that handle high data throughput. * **Embedded Computing:** Providing cooling for ARM or x86 processors in compact enclosures. * **Power Modules:** Dissipating heat from large MOSFET arrays or voltage regulators. --- ### 4.
