The **ATS-21H-143-C1-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 failure. --- ### 1. Technical Specifications Below are the primary electronic and physical specifications for this part: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. | | **Material** | Aluminum (Blue Anodized) | | **Thermal Resistance** | 7.28°C/W @ 100 LFM (Linear Feet per Minute) | | **Attachment Method** | pushPIN™ (Brass/Plastic pins) | | **Dimensions (L x W x H)** | 30mm x 30mm x 20mm | | **Fin Style** | High-Performance Cross-Cut (Blue Anodized) | | **Spring Type** | Stainless Steel (ATS-PP-09) | --- ### 2. Design and Engineering Features #### A. The pushPIN™ Attachment System The part number suffix indicates the use of the **pushPIN™** system. This is a mechanical mounting mechanism that provides: * **Constant Pressure:** A high-tension spring ensures that the heat sink maintains a consistent interface with the electronic component. * **Simplified Installation:** Pre-drilled holes in the PCB allow for quick assembly without complex tools. #### B. Thermal Interface Material (TIM) The "R0" at the end of the part number typically signifies the pre-applied thermal material. * **Performance:** It uses a phase-change material or high-performance thermal grease to fill microscopic air gaps between the heat sink base and the electronic chip. #### C. Cross-Cut Fin Design Unlike straight-fin heat sinks, this part features a **cross-cut** pattern. This is electronically advantageous because: * It handles **multi-directional airflow**, making it ideal for crowded PCBs where air may not flow in a single straight path. * It increases the surface area for heat radiation without increasing the physical footprint. --- ### 3. Application Use Cases This specific component is used in the following electronic environments: 1. **Telecommunications:** Cooling small processors in routers and switches. 2. **Embedded Systems:** Protecting microcontrollers in industrial automation. 3. **Power Supplies:** Dissipating heat from MOSFETs or voltage regulators. ---
