The **ATS-03D-148-C2-R0** is a high-performance **heat sink** manufactured by Advanced Thermal Solutions (ATS). While it is not an active electronic component (like a chip), it is a critical thermal management part used to dissipate heat from electronic devices like CPUs, GPUs, or power modules. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature used by ATS to define the dimensions and thermal properties of the heat sink. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. | | **Series** | pushPIN™ | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 35.00mm x 35.00mm x 15.00mm | | **Attachment Method** | Push-Pin (Plastic or Brass) | | **Thermal Resistance** | 8.59°C/W (Unducted Flow @ 100 LFM) | --- ### 2. Design and Component Breakdown #### A. The Fin Profile This model uses a **Cross-Cut** fin design. * **Purpose:** Allows for multi-directional airflow. Unlike straight fins that require air to move in one direction, cross-cut fins are efficient even if the air is turbulent or coming from a side angle. * **Surface Area:** The 15mm height provides a balance between low-profile requirements and high surface area for heat exchange. #### B. The Attachment Mechanism (pushPIN™) Instead of using messy thermal adhesives or complex screws, this part uses the **pushPIN™** system: * **Spring-Loaded:** Provides precise pressure (Pre-assembled with a stainless steel spring). * **Hardware:** Usually paired with a flexible plastic or durable brass pin that snaps into pre-drilled holes on the PCB (Printed Circuit Board). #### C. Thermal Interface Material (TIM) * **Pre-Applied:** This specific part usually comes with **T766** thermal phase-change material or similar grease pre-applied to the base. * **Efficiency:** This ensures there are no air gaps between the electronic component (heat source) and the aluminum base. --- ### 3. Application Use Cases This heat sink is typically found in the following electronic environments: 1. **Telecommunications:** Cooling small processors in routers and switches. 2. **Embedded Systems:** Industrial PCs where space is limited but heat generation is high. 3. **Power Electronics:** Dissipating heat from MOSFETs or voltage regulators. --- ### 4. Thermal Performance Comparison Thermal resistance is measured in **°C/W** (lower is better). | Airflow (LFM) | 100 | 200 | 300 | 400 | 500 | | :--- | :--- | :--- | :--- | :--- | :--- | | **Resistance (°C/W)** | 8.59 | 4.85 | 3.84 | 3.32 | 2.98 |
