The **ATS-P2-166-C2-R0** is a specific part number for a high-performance **Heat Sink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "pushPIN™" thermal management series designed to cool electronic components like CPUs, GPUs, and other high-heat-generating ICs. --- ### 1. Technical Specifications The part number encodes specific data regarding its physical dimensions, thermal performance, and mounting style. | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Heat Sink Type** | pushPIN™ Heat Sink Assembly | | **Fin Type** | Fine Pitch (maximizes surface area) | | **Dimensions (L x W x H)** | 25mm x 25mm x 15mm | | **Thermal Resistance** | 12.18°C/W (at 100 LFM) | | **Mounting Hardware** | Push-Pin (Plastic or Brass) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Breakdown of the Part Number Advanced Thermal Solutions uses a structured naming convention: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **P2:** Series designation (likely related to the pin/attachment style). * **166:** Specific model profile and size configuration. * **C2:** Finish and material code (typically indicates Blue Anodized Aluminum). * **R0:** Revision code (Standard product version). --- ### 3. Electronic Design Considerations When integrating this part into a PCB design, engineers focus on the following electronic/mechanical factors: #### A. Thermal Management This heat sink is categorized as **Passive Cooling**. It relies on natural or forced convection (fans) to dissipate heat away from the semiconductor. With a height of 15mm, it is ideal for compact electronic enclosures where vertical space is limited. #### B. The pushPIN™ System The "P2" designation refers to the attachment mechanism. Instead of using messy adhesives or permanent solder, it uses a **spring-loaded push-pin**. * **Ease of Maintenance:** Can be removed and re-installed easily. * **Pressure Control:** The springs ensure consistent pressure on the chip, which optimizes the performance of the Thermal Interface Material (TIM). #### C. Airflow Orientation The fin design is optimized for specific airflow patterns. Because it uses a **Fine-Pitch** fin geometry, it performs significantly better in "forced" airflow environments (where a fan is blowing air through the fins) rather than "natural" convection environments. --- ### 4. Typical Applications * **Networking Equipment:** High-speed routers and switches. * **Embedded Systems:** Industrial PCs and controllers. * **Power Electronics:** Voltage regulators or MOSFET arrays generating concentrated heat.
