The **ATS-03A-159-C2-R0** is a high-performance **Heat Sink** manufactured by Advanced Thermal Solutions (ATS) as part of their "push-pin" series. This component is designed to provide thermal management for electronic integrated circuits (ICs), such as CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics: | Attribute | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Brass) | | **Spring Type** | Compression Spring | | **Dimensions (L x W x H)** | 45mm x 45mm x 20mm | | **Fin Style** | Straight Fin | | **Thermal Resistance** | ~2.09°C/W (at 200 LFM) | --- ### 2. Electronic/Thermal Functionality This part is a **passive cooling** component. Its primary electronic purpose is to increase the surface area of a semiconductor package to dissipate heat more efficiently into the surrounding air. * **Thermal Interface Material (TIM):** The "R0" suffix indicates that the unit typically comes with **T766** pre-applied phase change material or a similar thermal pad, ensuring a low-resistance path for heat to travel from the chip to the aluminum. * **Airflow Dependency:** Because it uses a straight-fin design, it is optimized for systems with **forced air cooling** (fans). The straight channels allow air to pass through with minimal pressure drop. --- ### 3. Mechanical Components The assembly consists of three main sub-parts beyond the heat sink itself: 1. **Push-Pins:** Plastic or brass pins that snap into pre-drilled holes on a PCB (usually 3.0mm holes). 2. **Springs:** Provide constant downward pressure (clamp force), which is critical for maintaining a consistent contact layer between the heat sink and the electronic component. 3. **The Fin Array:** 45x45mm footprint provides a large dissipation area while fitting standard high-power electronic packages. --- ### 4. Common Applications * **Networking Gear:** Switches and Routers. * **Embedded Systems:** Industrial PC boards. * **Power Supplies:** Cooling MOSFETs or Voltage Regulators.
