The **ATS-19B-50-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **maxiFLOW™** series, designed to dissipate heat from electronic components like CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Attribute | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Material** | Aluminum (Black Anodized) | | **Attachment Method** | pushPIN™ | | **Dimensions (L x W x H)** | 45mm x 45mm x 15mm | | **Thermal Resistance** | 1.88°C/W (at 200 LFM) | | **Flow Direction** | High-performance flared fin pattern | --- ### 2. Design Features The "electronic" functionality of this part is passive, focusing on heat transfer to prevent semiconductor failure: * **Flared Fin Design:** The fins spread outward to increase the surface area available for convection. This reduces pressure drop and increases the efficiency of airflow from cooling fans. * **pushPIN™ Attachment:** This model uses a tool-free attachment system consisting of a plastic or brass pin and a compression spring. This ensures a precise amount of force is applied to the chip for optimal thermal contact. * **Thermal Interface Material (TIM):** This part usually comes with a pre-applied high-performance thermal pad (often **T766**), which fills microscopic air gaps between the component and the heat sink. --- ### 3. Application in Circuitry In an electronic system, the ATS-19B-50-C2-R0 is typically used for: 1. **BGA Components:** Large Ball Grid Array chips that generate significant heat. 2. **Power Electronics:** Voltage regulators or power modules. 3. **High-Speed Data Centers:** Used in environments where forced air (fans) is consistently present to take advantage of the flared fin design. --- ### 4. Thermal Performance Comparison Thermal resistance ($R_{th}$) determines how much the temperature rises per Watt of power: | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 3.44 | | 200 (1.0 m/s) | 1.88 | | 400 (2.0 m/s) | 1.15 | | 600 (3.0 m/s) | 0.82 |
