The **ATS-19D-101-C3-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heat sink**. These parts are critical in preventing integrated circuits (ICs) and CPUs from overheating. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Thermal Resistance** | 6.77°C/W @ 100 LFM | | **Dimensions (L x W x H)** | 45mm x 45mm x 30mm | | **Fin Style** | Straight Fin | --- ### 2. Breakdown of Electronic Functions #### A. Thermal Dissipation (The Core Function) This part acts as a passive heat exchanger. It increases the surface area of a hot electronic component (like a microprocessor or FPGA), allowing the surrounding air to carry away heat more efficiently. The **30mm height** provides a large volume for heat vertical dispersion. #### B. Blue Anodized Finish The blue anodization is not just for aesthetics. It provides: 1. **Corrosion Resistance:** Protects the aluminum from oxidation. 2. **Electrical Insulation:** Provides a thin non-conductive layer on the surface. 3. **Enhanced Emissivity:** Improves the radiant heat transfer compared to raw aluminum. #### C. Push-Pin Mounting System The "19D" and "R0" designations refer to the specific mounting hardware. - It uses a **plastic push-pin** and **compression spring** mechanism. - This ensures constant pressure (clamping force) between the heat sink and the chip, which is vital for maintaining a consistent thermal interface. --- ### 3. Usage in Electronic Assemblies To function correctly within a circuit, this part requires: 1. **TIM (Thermal Interface Material):** Usually pre-applied as a "T766" phase-change material or thermal grease to fill microscopic air gaps between the chip and the aluminum base. 2. **PCB Hole Pattern:** The motherboard/PCB must have specific drilled holes to accommodate the push-pins. 3. **Airflow:** Designed for "cross-cut" or "straight" airflow environments, typically used alongside a system cooling fan. ---
