The **ATS-19B-76-C2-R0** is a high-performance 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 they operate within safe temperature limits. --- ### 1. Technical Specifications Below is a breakdown of the physical and thermal characteristics of this specific part: | Feature | Specification | | :--- | :--- | | **Product Series** | pushPIN™ | | **Heat Sink Type** | Straight Fin | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 25mm x 25mm x 15mm | | **Thermal Resistance** | 11.57 °C/W (@ 100 LFM) | | **Attachment Method** | Push-Pin (Plastic or Brass) | | **Interface Material** | T766 (High-performance Thermal Phase Change) | --- ### 2. Key Components & Construction #### A. The Fin Design (Straight Fin) The "Straight Fin" geometry is optimized for **forced air convection**. It allows air from a fan to flow through the channels efficiently. While simple in design, the density and height of the fins are calculated to maximize surface area for heat transfer within a small footprint. #### B. The Push-Pin Attachment The "-R0" suffix refers to the specific attachment system. This model uses a **spring-loaded push-pin** mechanism: * **Ease of Install:** It requires pre-drilled holes in the PCB. * **Constant Pressure:** The spring ensures the heat sink stays firmly pressed against the chip, which is critical for minimizing thermal resistance. #### C. Thermal Interface Material (TIM) The unit comes pre-applied with **T766**. This is a thermal grease or phase-change material that fills microscopic air gaps between the component and the heat sink base, significantly improving heat conductivity. --- ### 3. Part Number Decoder Understanding the nomenclature helps in identifying its properties: | Segment | Meaning | | :--- | :--- | | **ATS** | Advanced Thermal Solutions (Manufacturer) | | **19B** | Series/Footprint (25mm x 25mm) | | **76** | Specific Design Profile/Fin height | | **C2** | Performance class / Material grade | | **R0** | Revision or specific mounting kit (Standard Push-Pin) | --- ### 4. Application Use-Cases * **Small Form Factor (SFF) PC Boards:** Due to its 25mm x 25mm size. * **Embedded Systems:** Cooling microcontrollers or FPGAs. * **Networking Gear:** Cooling small chips inside routers or switches.
