The **ATS-03A-151-C2-R0** is a high-performance heat sink component manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push-pin" series designed for efficient cooling of integrated circuits (ICs) and other electronic components. --- ## Technical Specifications Below are the primary electronic and mechanical specifications for this part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Thermal Resistance (Unducted)** | 3.93 °C/W @ 100 LFM | | **Thermal Resistance (Ducted)** | 2.36 °C/W @ 100 LFM | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 35.00mm x 35.00mm x 20.00mm | | **Attachment Method** | Push-Pin (Brass) | --- ## Electronic & Thermal Role The ATS-03A-151-C2-R0 acts as a **passive thermal management component**. In electronics, its purpose is to increase the surface area of a heat-generating component to prevent thermal throttling or hardware failure. ### 1. Thermal Resistance Breakdown The performance of this heat sink is measured by its ability to transfer heat from the junction to the ambient air ($R_{th}$). * **Low Airflow:** At 200 LFM (Linear Feet per Minute), the resistance drops to **2.63 °C/W**. * **High Airflow:** At 700 LFM, the resistance is significantly reduced to **1.51 °C/W**. ### 2. Attachment Mechanism The "R0" suffix indicates the mounting hardware. This model uses a **push-pin** system: * **Springs:** Specifically designed to provide precise pressure (Force) to ensure maximum contact between the heat sink and the electronic chip. * **Interface:** It is typically paired with a **Thermal Interface Material (TIM)** like a pre-applied Phase Change Material or thermal grease. --- ## Common Applications This specific size and height (20mm) are commonly found in the following electronic systems: * **Networking Gear:** Switches and routers. * **Power Supplies:** Cooling MOSFETs or Voltage Regulators. * **Processors:** Chipsets, BGA (Ball Grid Array) packages, and FPGAs. --- ## Comparison with Similar Models ```python # Comparison of Thermal Resistance (Low vs High Airflow) models = { "ATS-03A-151-C2-R0": {"100_LFM": 3.93, "700_LFM": 1.51}, "ATS-03A-150-C2-R0": {"100_LFM": 4.82, "700_LFM": 1.73} } for model, stats in models.items(): print(f"Model: {model} | Max Res: {stats['100_LFM']} | Min Res: {stats['700_LFM']}") ```
