The **ATS-18B-176-C2-R0** is a high-performance heat sink manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **maxiFLOW™** product line, designed specifically for high-velocity airflow environments to cool electronic components such as processors, FPGAs, and ASICs. ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-18B-176-C2-R0 | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | pushPIN™ | | **Fin Style** | XCUT (Tapered Fin) | | **Dimensions (L x W x H)** | 45mm x 45mm x 10mm | | **Thermal Resistance** | 4.40°C/W (at 200 LFM) | | **Pressure Drop** | High-efficiency design for low pressure | --- ### 2. Key Electronic & Mechanical Features #### A. XCUT Fin Geometry The "XCUT" design features a tapered fin pattern. This is critical for electronics because it increases the surface area for heat dissipation while allowing the sink to be used in various airflow directions (omni-directional), unlike traditional straight-fin sinks that require specific alignment. #### B. pushPIN™ Attachment System Rather than using messy thermal adhesives, this part uses a mechanical **pushPIN™** system. * **Springs:** Provides a precise, consistent "Pre-Load" force to ensure the thermal interface material (TIM) is compressed evenly across the chip. * **Reliability:** Resistant to vibration and shock, making it suitable for industrial or telecommunications hardware. #### C. Thermal Interface Material (TIM) The "C2" designation in the part number typically refers to the **ATS-Thermal Tape** or phase-change material pre-applied to the base. This ensures that microscopic air gaps between the component (CPU/GPU) and the heat sink are filled, maximizing heat transfer. --- ### 3. Application Use Cases This specific heat sink is typically found in: 1. **Network Switches/Routers:** Where high-velocity fans are present. 2. **Embedded Systems:** Small form factor boards requiring low-profile (10mm height) cooling. 3. **Power Supplies:** Cooling MOSFETs or power regulators. ---
