The **ATS-19B-174-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 components like CPUs, GPUs, or power transistors to prevent thermal throttling or failure. --- ## 1. Technical Specifications The following table outlines the physical and thermal characteristics of this specific part number: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Material** | Aluminum | | **Attachment Method** | Push-Pin (Plastic) | | **Thermal Resistance (Flowing)** | 4.02 °C/W @ 100 LFM | | **Thermal Resistance (Static)** | 2.11 °C/W @ 700 LFM | | **Dimensions (L x W)** | 30.00 mm x 30.00 mm | | **Height (Height off Base)** | 25.00 mm | | **Fin Type** | Fine Pitch (Cross-Cut) | --- ## 2. Component Analysis This part is not an active electronic circuit but a **passive cooling component**. Its design is optimized for specific airflow environments: ### A. Material and Coating * **Aluminum:** Lightweight with high thermal conductivity. * **Blue Anodized Finish:** The "C2" in the part number indicates a blue anodized finish, which provides corrosion resistance and slightly improves radiant heat transfer. ### B. pushPIN™ Attachment System The "19B" designation refers to the specific attachment mechanism. It uses a **spring-loaded push-pin** system which: * Provides consistent pressure across the interface for optimal heat transfer. * Eliminates the need for messy adhesives. * Features pre-drilled holes for easy installation on a PCB. ### C. Thermal Interface Material (TIM) This specific model usually comes with **T766** pre-applied thermal phase-change material or grease on the base. This ensures there are no air gaps between the electronic chip and the heat sink. --- ## 3. Application Use Cases The ATS-19B-174-C2-R0 is typically used in the following electronic assemblies: 1. **Telecommunications:** Cooling of high-speed networking chips. 2. **Embedded Systems:** Industrial PCs where space is limited but vertical height (25mm) is available. 3. **Power Electronics:** Dissipating heat from Voltage Regulator Modules (VRMs). ---
