The **ATS-19H-47-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It is part of the "push pin" series designed for securing the cooling element directly to a Printed Circuit Board (PCB). --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Dimensions (L x W)** | 25mm x 25mm | | **Height** | 30mm | | **Thermal Resistance** | 9.30°C/W (at 100 LFM) | | **Flow Orientation** | Vertical Fin (High Aspect Ratio) | --- ### 2. Key Electronic & Mechanical Components #### A. The Heat Sink Body The body is made of **extruded aluminum**. Aluminum is chosen for its high thermal conductivity and lightweight properties. The "Blue Anodized" finish is not just aesthetic; it protects the aluminum from corrosion and slightly improves emissivity for radiant heat transfer. #### B. The Push-Pin Fastener Instead of using messy thermal adhesives or screws that require tools, this part uses a **spring-loaded push-pin mechanism**. * **The Pin:** Usually made of nylon or brass. * **The Spring:** Provides consistent pressure (clamping force) to ensure the heat sink remains in flush contact with the electronic chip (CPU, GPU, or MOSFET). #### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates that the part comes with a **pre-applied Thermal Interface Material**. This is a phase-change material or a thermal pad located on the base of the heat sink to fill microscopic air gaps between the component and the sink. --- ### 3. Application Use Cases This specific model is designed for small-form-factor electronics where vertical space is available but PCB real estate is limited (25x25mm footprint). 1. **Telecommunications:** Cooling for small network switches or routers. 2. **Embedded Systems:** High-speed processors in industrial controllers. 3. **Power Electronics:** Cooling for voltage regulator modules (VRMs). --- ### 4. Thermal Performance Comparison Thermal resistance ($R_{th}$) determines how efficiently the part moves heat away from the silicon. | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (Natural) | 9.30 | | 300 (Forced) | 4.30 | | 500 (High Speed) | 3.50 |
