The **ATS-19H-129-C2-R0** is a high-performance electronic cooling component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "pushPIN™" series, designed for efficient thermal management of surface-mount electronic components. --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of this specific part: | Feature | Specification | | :--- | :--- | | **Product Series** | pushPIN™ | | **Material** | Aluminum | | **Fin Type** | Straight Fin | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W)** | 54.00 mm x 54.00 mm | | **Height (Height Off Base)** | 10.00 mm | | **Thermal Resistance (Flowing)** | 2.50 °C/W @ 200 LFM | | **Thermal Resistance (Static)** | 8.68 °C/W @ 0 LFM | | **Thermal Interface Material** | T766 (Pre-applied) | --- ### 2. Physical Design & Construction * **Fin Configuration:** The **Straight Fin** design allows for maximum airflow through the sink, which is ideal for systems with high-velocity air cooling. * **Low Profile:** With a height of only **10.00 mm**, it is suitable for dense PCB layouts or 1U server chassis where vertical space is limited. * **Material:** Made from **Blue Anodized Aluminum**, providing high thermal conductivity and corrosion resistance. --- ### 3. Mounting System (pushPIN™) The "C2" in the part number refers to the specific attachment hardware: 1. **Springs:** Uses a stainless steel spring to provide consistent pressure. 2. **Pins:** Plastic or brass pins secure the heat sink to pre-drilled holes in the PCB. 3. **Pressure:** This system ensures the heat sink remains in tight contact with the chip, optimizing heat transfer even during vibration or mechanical shock. --- ### 4. Thermal Performance Data Performance varies based on the airflow (measured in Linear Feet per Minute - LFM): | Air Velocity (m/s) | 0.5 (100 LFM) | 1.0 (200 LFM) | 2.0 (400 LFM) | 3.0 (600 LFM) | | :--- | :--- | :--- | :--- | :--- | | **Thermal Resistance** | 8.68 °C/W | 2.50 °C/W | 1.59 °C/W | 1.25 °C/W |
