The **ATS-04D-46-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It belongs to the "pushPIN™" series, designed for efficient heat dissipation in compact electronic environments. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Al6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Flow Pattern** | Vertical-fin (Straight Fin) | | **Dimensions (L x W x H)** | 25mm x 25mm x 15mm | | **Thermal Resistance** | 11.72 °C/W (at 100 LFM) | | **Thermal Interface Material** | T412 (Phase Change Material) | --- ### 2. Design and Engineering Features ### A. Fin Geometry (Straight Fin) This heat sink uses a **Straight Fin** design. * **Performance:** It is optimized for "high-velocity" airflow environments where the air can be forced through the channels efficiently. * **Suitability:** Best used in scenarios where the direction of airflow is consistent. ### B. pushPIN™ Attachment System Instead of using adhesive tapes or simple clips, this part uses the ATS pushPIN™ system: * **Pressure:** Uses a flexible "spring" mechanism to ensure consistent pressure between the heat sink and the component (CPU/GPU/ASIC). * **Reliability:** Highly resistant to shock and vibration compared to adhesive solutions. * **Installation:** Uses pre-drilled holes in the PCB for a secure mechanical lock. ### C. Thermal Interface Material (T412) The part comes pre-applied with **T412**, a high-performance thermal pad/coating. * It fills the microscopic air gaps between the heat sink base and the electronic component. * It ensures maximum heat transfer efficiency without requiring the manual application of thermal grease. --- ### 3. Application Use-Cases The **ATS-04D-46-C3-R0** is typically used for cooling the following electronic components: 1. **Small Form Factor (SFF) ICs:** Voltage regulators, small CPUs, or motor drivers. 2. **Network Hardware:** Transceivers and small-node chipsets. 3. **Embedded Systems:** Industrial PCs where mechanical stability is required due to vibration.
