The **ATS-18A-208-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the *push-pin* attachment series designed for cooling electronic components like CPUs, GPUs, and power modules. --- ## 1. Technical Specifications Below are the primary electronic and physical specifications for this part: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Product Series** | pushPIN™ | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Thermal Resistance** | 6.69° C/W (at 100 LFM) | | **Attachment Method** | Push-Pin (Plastic) | | **Flow Orientation** | Straight Fin | --- ## 2. Component Breakdown ### A. Material and Design * **Aluminum 6063:** This alloy is chosen for its excellent thermal conductivity and structural integrity. * **Straight Fin Geometry:** The fins are arranged in a straight pattern to allow air to flow through the channel. This is ideal for systems with directed airflow (forced convection). * **Blue Anodized Coating:** This is not just for aesthetics; the anodization protects the aluminum from corrosion and slightly increases the surface emissivity, which aids in radiant cooling. ### B. Thermal Performance The efficiency of the heat sink depends on the airflow (measured in Linear Feet per Minute - LFM). As airflow increases, the thermal resistance decreases: * **@ 100 LFM:** 6.69° C/W * **@ 700 LFM:** 1.74° C/W ### C. Mechanical Dimensions Understanding the physical footprint is critical for PCB layout: * **Width/Length:** 45mm x 45mm * **Height:** 10mm (Low profile design) * **Hole Pattern:** 38mm x 38mm (Pitch for the push-pins) --- ## 3. Application Context The **ATS-18A-208-C2-R0** is typically used in: 1. **Telecommunications:** Cooling network switches and routers. 2. **Embedded Systems:** Industrial PCs where vertical space is limited. 3. **Power Supplies:** Dissipating heat from MOSFETs or voltage regulators. --- ## 4.
