The **ATS-18D-11-C2-R0** is a high-performance electronic thermal management component. Specifically, it is an **Advanced Thermal Solutions (ATS) push-pin heatsink** designed for cooling integrated circuits (ICs) such as CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Heatsink Type** | Push-Pin (Spring-loaded) | | **Material** | Aluminum (Blue Anodized) | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 18.74°C/W @ 100 LFM | | **Attachment Method** | Plastic Push-Pin with Brass Springs | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Dimension Breakdown The physical footprint is critical for PCB layout planning: * **Length:** 50.00 mm * **Width:** 50.00 mm * **Height:** 12.70 mm (Low profile) * **Pitch (Hole-to-Hole):** 43.00 mm --- ### 3. Component Breakdown The assembly consists of four primary sub-components: 1. **Aluminum Body:** Extruded aluminum allows for high thermal conductivity while remaining lightweight. The blue anodized finish increases emissivity and protects against corrosion. 2. **Straight Fins:** Optimized for longitudinal airflow. These are best suited for systems with a dedicated cooling fan providing directional air. 3. **Push-Pin Fasteners:** These are designed to provide a specific amount of "clamping force" (pressure). This ensures the heatsink remains in constant contact with the chip, even during mechanical vibration. 4. **T766 TIM:** This is a phase-change material or high-performance thermal pad pre-applied to the base. It fills microscopic air gaps between the chip surface and the heatsink base to maximize heat transfer. --- ### 4. Key Applications * **Networking Equipment:** Routers, switches, and base stations. * **Embedded Systems:** Industrial PCs where vertical space is limited (12.7mm height). * **Power Supplies:** Cooling voltage regulators or power MOSFETs. ---
