The **ATS-18A-40-C3-R0** is a specific electronic component belonging to the thermal management category. It is a high-performance **heat sink** manufactured by Advanced Thermal Solutions (ATS). --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of this specific part: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Heat Sink Type** | Push-pin Heat Sink | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | Push-Pin (Brass) | | **Dimensions** | 45mm x 45mm x 25mm | | **Thermal Resistance** | 1.47 °C/W (at 200 LFM) | | **Fin Style** | Straight Fin | --- ### 2. Design and Components This part is designed for PCB-level cooling of integrated circuits (ICs) and processors. Its construction consists of several key electronic/mechanical parts: * **Heat Sink Body:** A block of aluminum extruded with a "Straight Fin" pattern. This increases the surface area for heat dissipation into the surrounding air. * **Thermal Interface Material (TIM):** This part usually comes pre-applied with **T412**, a high-performance thermal pad that fills microscopic air gaps between the component (CPU/GPU) and the heat sink. * **Push-Pin Mechanism:** Uses a spring-loaded brass pin system. This provides a consistent "pressure force" on the electronic chip, ensuring optimal heat transfer without cracking the silicon. * **Blue Anodized Finish:** Not just for aesthetics; the anodized layer provides a level of electrical insulation and corrosion resistance. --- ### 3. Application and Usage The **ATS-18A-40-C3-R0** is typically found in: 1. **Telecommunications Equipment:** For cooling high-speed network processors. 2. **Embedded Systems:** Industrial PCs where fan space is limited. 3. **Power Electronics:** Dissipating heat from MOSFETs or voltage regulators. --- ### 4.
