The **ATS-04F-209-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "push pin" series designed to provide efficient cooling for electronic components like processors, GPUs, and power modules. ### 1. Technical Specifications The following table highlights the core mechanical and thermal properties of this specific part number: | Property | Description | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push Pin (Plastic/Brass) | | **Thermal Resistance** | 6.27°C/W (Unducted Flow @ 200 LFM) | | **Dimensions** | 70mm x 70mm x 10mm | | **Fin Style** | XC-Cut (Cross-cut) | --- ### 2. Key Features and Design * **XC-Cut Fin Pattern:** The "XC-Cut" design features a cross-cut pattern that allows for multi-directional airflow. This is critical in cramped electronic enclosures where air may not flow in a straight line. * **Low Profile:** With a height of only 10mm, this heat sink is ideal for 1U servers or low-profile embedded systems. * **Pre-applied Thermal Interface Material (TIM):** This part usually comes with **T766** phase-change material or similar, which ensures optimal heat transfer from the chip to the aluminum base without needing manual paste application. * **Secure Attachment:** The "04F" designation refers to the specific push-pin and spring combination used to apply consistent pressure on the high-power component, preventing air gaps. --- ### 3. Applications The ATS-04F-209-C2-R0 is commonly used in: 1. **Telecommunications:** Cooling for ASICs and FPGAs in networking switches. 2. **Computing:** Chipset cooling on motherboards or high-speed storage controllers. 3. **Power Electronics:** Dissipating heat from large MOSFET arrays or power converters. --- ### 4. Thermal Performance Comparison Thermal resistance varies based on the velocity of the airflow (LFM - Linear Feet per Minute): | Airflow (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 100 | 0.5 | 9.37 | | 200 | 1.0 | 6.27 | | 400 | 2.0 | 4.35 | | 600 | 3.0 | 3.48 |
