### Overview of ATS-16D-166-C3-R0 The **ATS-16D-166-C3-R0** is a high-performance **Heat Sink** manufactured by **Advanced Thermal Solutions (ATS)**. It belongs to the **pushPIN™** series, which is designed for secure, standardized attachment to Printed Circuit Boards (PCBs). --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Part Number** | ATS-16D-166-C3-R0 | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance (Unducted)** | 12.30 °C/W @ 100 LFM | | **Thermal Resistance (Ducted)** | 2.50 °C/W @ 100 LFM | --- ### Key Components and Design #### 1. Heat Sink Geometry The device uses a **Flat Fin** design. This is optimized for straight-line airflow, providing a large surface area for heat dissipation relative to its compact footprint. * **Length/Width:** 25.00 mm x 25.00 mm * **Height:** 15.00 mm (Off-the-shelf profile) #### 2. Attachment Mechanism: pushPIN™ Instead of using messy adhesives or thermal tapes, this part uses a mechanical attachment system consisting of: * **Brass/Plastic Pins:** Used to anchor the sink to the PCB holes. * **Compression Springs:** These provide precise, uniform pressure (Pre-assembled) across the interface, ensuring maximum contact with the component being cooled. #### 3. Thermal Interface Material (TIM) The part comes with **T412** thermal interface material pre-applied to the base. This eliminates the need for manual application of thermal paste and ensures consistent thermal conductivity between the chip and the aluminum base. --- ### Application and Use Cases This electronic part is typically found in: * **Networking Equipment:** Cooling small processors in routers or switches. * **Embedded Systems:** High-heat output microcontrollers. * **Power Supplies:** Heat dissipation for MOSFETs or voltage regulators. --- ### Performance under Airflow The efficiency of this heat sink is highly dependent on the air velocity (Measured in Linear Feet per Minute - LFM): | Velocity (LFM) | 100 | 200 | 300 | 400 | 500 | | :--- | :--- | :--- | :--- | :--- | :--- | | **Resistance (°C/W)** | 12.30 | 8.46 | 6.96 | 6.08 | 5.50 |
