The **ATS-02A-140-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "pushPIN™" component series, designed for cooling electronic components such as CPUs, GPUs, and power transistors. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Body), Blue Anodized (Finish) | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Heat Sink Type** | Straight Fin | | **Dimensions (L x W x H)** | 25.00mm x 25.00mm x 25.00mm | | **Thermal Resistance** | 7.28 °C/W (Unducted Flow @ 100 LFM) | | **Compatibility** | Universal (based on hole pattern) | --- ### 2. Component Breakdown #### A. The Heat Sink Body The core is made of aluminum, chosen for its high thermal conductivity and lightweight properties. The **Straight Fin** design allows for vertical airflow, making it ideal for systems with concentrated air movement. #### B. The PushPIN™ Mounting System Instead of using messy adhesives or complicated brackets, this part uses a spring-loaded pin mechanism: * **Ease of Install:** Allows for quick, tool-free installation to the PCB. * **Consistent Pressure:** The springs ensure even pressure across the thermal interface material (TIM) for maximum heat transfer. * **Reliability:** Highly resistant to vibration compared to simple clip-on sinks. #### C. Thermal Interface Material (TIM) The "R0" suffix usually denotes that the part comes with a pre-applied **Thermal Interface Material** (typically a high-performance phase-change material or grease). This fills the microscopic air gaps between the electronic chip and the heat sink base. --- ### 3. Thermal Performance Metrics The effectiveness of this part depends on the airflow (measured in Linear Feet per Minute - LFM): | Airflow Velocity | Thermal Resistance (Unducted) | | :--- | :--- | | 100 LFM (0.5 m/s) | 7.28 °C/W | | 300 LFM (1.5 m/s) | 4.23 °C/W | | 500 LFM (2.5 m/s) | 3.44 °C/W | --- ### 4.
