The **ATS-H1-74-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heatsink**. It is designed to dissipate heat from electronic integrated circuits (ICs) such as CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by Advanced Thermal Solutions. Here is the breakdown of its physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (High thermal conductivity) | | **Finish** | Blue Anodized (Corrosion resistance/high emissivity) | | **Dimensions** | 25mm x 25mm x 15mm | | **Attachment Type** | Push-Pin (Spring-loaded) | | **Thermal Interface** | T766 (Pre-applied Phase Change Material) | | **Fin Style** | Straight Fin | --- ### 2. Key Electronic Components Breakdown #### A. The Heatsink Body (Heat Dissipation) The core component is made of extruded aluminum. The "Straight Fin" design is optimized for **forced-air cooling** (airflow from a fan). By increasing the surface area, it allows the surrounding air to carry away the heat generated by the semiconductor device underneath. #### B. Push-Pin Mounting Mechanism Unlike adhesive-based heatsinks, the `H1` designation indicates a mechanical attachment: * **Plastic Push-Pins:** Flexible fasteners that snap into holes on the Printed Circuit Board (PCB). * **Compression Springs:** These provide constant, uniform pressure on the electronic chip, ensuring optimal contact and preventing the heatsink from shifting during mechanical shock or vibration. #### C. Thermal Interface Material (TIM) The "R0" suffix usually denotes the specific TIM applied to the base. * This model uses **T766 Phase Change Material**. * **Function:** As the electronic part heats up, this material softens to fill microscopic air gaps between the chip and the heatsink, significantly reducing thermal resistance. --- ### 3. Typical Applications This part is commonly found in the following electronic environments: * **Networking Gear:** Routers, switches, and high-speed modems. * **Industrial PCs:** Small form-factor motherboards where space is limited. * **Embedded Systems:** Protecting sensitive microprocessors from overheating in enclosed housings. --- ### 4. Thermal Performance The efficiency of this part is measured by its **Thermal Resistance (Rθ)**. In a typical airflow environment (e.g., 200 LFM - Linear Feet per Minute), this heatsink can reduce the junction temperature of a chip significantly, preventing "thermal throttling" or hardware failure.
