The **ATS-03B-159-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the **pushPIN™** series, designed to provide efficient cooling for electronic components like CPUs, GPUs, and power modules. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions** | 45mm x 45mm x 20mm | | **Fin Type** | XCUT (Fine pitch cross-cut) | | **Thermal Resistance** | 10.70°C/W (at 1.0 m/s airflow) | | **Weight** | ~40 grams | --- ### 2. Component Design Breakdown #### A. The Heat Sink Body (XCUT Design) The "XCUT" geometry features a pattern of fins that are cut both horizontally and vertically. * **Surface Area:** This design maximizes the surface area available for heat dissipation. * **Airflow:** It is optimized for omnidirectional airflow, meaning it performs well even if the air direction is not perfectly aligned with the fins. #### B. The pushPIN™ Attachment System Instead of using messy adhesives or simple clips, this part uses a mechanical push-pin system: * **Springs:** Provides consistent pressure (Pre-assembled with a high-performance compression spring). * **Stability:** Ensures the heat sink remains in constant contact with the component surface, even during vibration or mechanical shock. #### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates that the part comes with **T766** thermal interface material (or a similar high-performance grease/pad) pre-applied to the base. This fills microscopic air gaps between the chip and the heat sink. --- ### 3. Thermal Performance Matrix Thermal resistance varies based on the velocity of the air passing through the fins (measured in Linear Feet per Minute - LFM): | Velocity (m/s) | Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 0.5 | 100 | 20.97 | | 1.0 | 200 | 10.70 | | 2.0 | 400 | 6.20 | | 3.5 | 700 | 4.30 | --- ### 4. Application Use Cases * **Embedded Systems:** Cooling microprocessors in industrial PCs. * **Telecommunications:** Regulating heat in high-speed routers and switches. * **Power Electronics:** Dissipating heat from MOSFETs or IGBTs in power supplies. ---
