The **ATS-04F-44-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 The following table outlines the physical and thermal properties of the component: | Feature | Specification | Details | | :--- | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions | P/N: ATS-04F-44-C3-R0 | | **Material** | Aluminum | Blue Anodized Finish | | **Dimensions** | 40mm x 40mm x 10mm | (L x W x H) | | **Fin Style** | Push-Pin / XC-Cut | Straight fins for airflow efficiency | | **Thermal Resistance** | 20.35 °C/W (Unducted) | Varies based on airflow (LFM) | | **Attachment** | Push-Pin | Features a brass spring-loaded mechanism | | **Thermal Interface** | T412 | Pre-applied thermal interface material | --- ### 2. Key Electronic Components & Design The "ATS-04F-44-C3-R0" is more than just a block of metal; it incorporates specific engineering features for electronic reliability: * **Push-Pin Mounting:** Unlike adhesive-based heat sinks, this uses a mechanical push-pin system. This ensures consistent pressure against the electronic chip, which optimizes heat transfer and allows for easier maintenance or replacement. * **XC-Cut Fin Profile:** The fins are designed with a cross-cut pattern. This allows for multi-directional airflow, making it ideal for electronic enclosures where the direction of the cooling fan might not be perfectly aligned with the heat sink. * **T412 Thermal Interface Material (TIM):** It comes with a pre-applied Phase Change Material (PCM). When the electronic component heats up, this material softens to fill microscopic air gaps between the chip and the heat sink, significantly reducing thermal resistance. --- ### 3. Thermal Performance Analysis The efficiency of this part depends heavily on the Linear Feet per Minute (LFM) of airflow provided by the system's fans: | Airflow (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 200 | 1.0 | 20.35 | | 400 | 2.0 | 11.83 | | 600 | 3.0 | 8.32 | | 800 | 4.0 | 6.72 | --- ### 4. Typical Applications * **Embedded Systems:** Cooling SoCs (System on Chips) in industrial controllers. * **Telecommunications:** Dissipating heat from high-speed networking processors. * **Power Supplies:** Cooling voltage regulators and power MOSFETs.
