The **ATS-18B-41-C2-R0** is a high-performance electronic thermal management component. Specifically, it is a **heat sink** designed by *Advanced Thermal Solutions (ATS)*, part of their push-pin series for PCB-level cooling. --- ### 1. Technical Specifications Below are the primary electronic and physical specifications for this part: | Feature | Specification | | :--- | :--- | | **Component Type** | Heat Sink (Passive) | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | Push-Pin (Plastic) with Spring | | **Dimensions** | 40mm x 40mm x 20mm | | **Thermal Resistance** | 10.03°C/W (Unducted @ 200 LFM) | | **Fin Style** | Straight Fin | | **Interface Material** | T766 (Phase Change Material) | --- ### 2. Breakdown of the Part Number The part number follows a specific nomenclature used by Advanced Thermal Solutions: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **18B:** Indicates the specific product series (Push-pin heat sink). * **41:** Refers to the physical dimensions (approx. 40mm width/length). * **20:** Refers to the height (20mm). * **C2:** Denotes the material and finish (typically aluminum with a blue anodized finish). * **R0:** Revision/Packaging code. --- ### 3. Key Electronic Functions While the heat sink itself does not carry an electrical charge, its role in an electronic circuit is critical: 1. **Thermal Dissipation:** It is designed to sit atop high-heat components such as CPUs, GPUs, FPGAs, or Power MOSFETs to dissipate heat into the surrounding air. 2. **Spring-Loaded Attachment:** The push-pin mechanism provides **consistent pressure**. In electronics, uniform pressure on the Die (the chip) is essential to prevent cracking while ensuring maximum contact with the thermal interface material. 3. **EMI Considerations:** The aluminum body can occasionally act as an EMI shield or, conversely, an antenna if not properly grounded or positioned relative to high-frequency components. 4. **Pre-applied TIM:** The "T766" phase-change material ensures low thermal impedance between the chip and the metal, improving the efficiency of heat transfer away from sensitive electronic junctions. --- ### 4. Typical Applications * **Network Switches/Routers:** Cooling high-speed processing chips. * **Industrial PCs:** Cooling embedded processors in tight enclosures. * **Power Supplies:** Managing heat for voltage regulators.
