The **ATS-01A-174-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the **pushPIN™** series, designed to provide efficient cooling for electronic components like CPUs, GPUs, and other high-heat integrated circuits. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics. Here is the breakdown: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 4.02 °C/W (at 100 LFM) | | **Dimensions (L x W x H)** | 35mm x 35mm x 15mm | | **Fin Pattern** | Fine Pitch (Cross-Cut) | --- ### 2. Key Electronic & Mechanical Components #### A. Thermal Interface Material (TIM) The "R0" suffix indicates that the heat sink comes pre-applied with a **T766 thermal phase-change material**. This eliminates the need for manual thermal paste application and ensures maximum heat transfer between the electronic component (die) and the aluminum base. #### B. The pushPIN™ Attachment System This is a specialized mounting mechanism designed for high-vibration environments. It consists of: * **Brass/Plastic Push Pins:** These snap into pre-drilled holes on the PCB. * **Compression Springs:** These provide precise, constant pressure (even load) across the electronic chip to prevent cracking while ensuring optimal thermal contact. #### C. Cross-Cut Fin Design Unlike straight-fin heat sinks, the ATS-01A-174-C2-R0 features a cross-cut pattern. In electronics, this is crucial because: * It allows for **omni-directional airflow**, meaning the cooling efficiency is less dependent on the direction of the system fan. * It increases the surface area for heat dissipation without increasing the physical footprint. --- ### 3. Application Use Cases This part is typically found in: * **Embedded Systems:** Industrial PCs and controllers. * **Networking Gear:** Switches and routers where vertical space (15mm height) is limited. * **Power Supplies:** Cooling MOSFETs or voltage regulators.
