The **ATS-19F-166-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of their "pushPIN™" series, designed for cooling integrated circuits (ICs) like CPUs, GPUs, or FPGAs. --- ## 1. Technical Specifications The following table summarizes the key physical and thermal properties of this component: | Property | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions** | 45mm x 45mm x 10mm | | **Thermal Resistance (Unducted)** | 12.30 °C/W @ 100 LFM | | **Thermal Resistance (Ducted)** | 2.50 °C/W @ 100 LFM | | **Thermal Interface Material** | T412 (Phase Change Material) | --- ## 2. Key Features & Electronic Function While a heat sink is a passive mechanical part, its role in an electronic circuit is critical for maintaining performance and reliability. ### Thermal Dissipation The primary function is to conduct heat away from a semiconductor device. The **C3** designation indicates it uses a high-performance Thermal Interface Material (TIM), which ensures minimal air gaps between the chip and the aluminum base. ### pushPIN™ Attachment System This specific part uses a specialized attachment mechanism: * **Precision Springs:** Provides consistent pressure to ensure optimal contact with the heat source. * **Nylon pushPINs:** These are non-conductive and prevent short-circuiting or mechanical stress on the PCB. ### Fin Design The part features a **straight fin** or **cross-cut** design (depending on the specific sub-batch) optimized for forced air cooling. Its low profile (10mm height) makes it ideal for electronics with restricted vertical space, such as 1U servers or flat-panel displays. --- ## 3.
