The **ATS-19F-191-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 ensure system stability. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic or Brass) | | **Thermal Resistance (Flowing)** | 2.90 °C/W @ 100 LFM | | **Thermal Resistance (Static)** | 6.12 °C/W (Unducted) | | **Dimensions** | 45mm x 45mm x 30mm | --- ### 2. Breakdown of the Component Parts The assembly of this part consists of several distinct electronic and mechanical elements: #### A. The Heat Sink Body (The Fin Array) This is the main aluminum block. It uses a **fine-pitch fin design** to maximize surface area. * **Thermal Conductivity:** High-grade aluminum efficiently pulls heat away from the PCB component. * **Blue Anodized Coating:** This provides corrosion resistance and slightly improves radiative heat transfer. #### B. The pushPIN™ Attachment System Instead of using messy adhesives or complicated brackets, this part uses the ATS pushPIN™ mechanism. * **Springs:** Provides consistent pressure (Contact Pressure) between the heat sink and the component to minimize air gaps. * **Pins:** Designed to fit into pre-drilled 3.175mm holes on a PCB. #### C. Thermal Interface Material (TIM) The "C2" in the part number typically denotes that the heat sink comes with a **pre-applied Thermal Interface Material**. * **Function:** It fills microscopic air gaps between the heat sink base and the electronic chip, significantly lowering thermal resistance. --- ### 3. Part Number Decoder Understanding the nomenclature helps identify its specific electronic application: | Segment | Meaning | | :--- | :--- | | **ATS-19** | Series/Style identifier | | **F** | Fine-pitch fin pattern | | **191** | Specific dimensional/design iteration | | **C2** | Thermal Performance Class (typically T766 or similar TIM) | | **R0** | RoHS Compliant (Lead-free) | --- ### 4. Typical Applications * **Telecommunications:** Cooling for high-speed routers and switches. * **Embedded Systems:** Industrial motherboards where vertical space allows for a 30mm height. * **Power Electronics:** Dissipating heat from MOSFETs or voltage regulators.
