The **ATS-55300D-C1-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It belongs to their "maxiFLOW™" product line, specifically designed for high-velocity airflow environments in electronic systems. --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of this specific component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Anodized Blue) | | **Dimensions** | 30.00mm x 30.00mm | | **Height** | 9.50mm | | **Attachment Method** | pushPIN™ (Brass Pins) | | **Thermal Resistance** | 5.80 °C/W (at 200 LFM) | | **Interface Material** | T766 (Thermal Phase Change Material) | | **Compliance** | RoHS and REACH Compliant | --- ### 2. Electronic Application & Function This part acts as a **passive cooling solution** for integrated circuits (ICs). Its primary role in an electronic circuit is: * **Heat Dissipation:** It increases the surface area of a semiconductor (like a BGA, CPU, or FPGA), allowing heat to transfer more efficiently to the surrounding air. * **Component Longevity:** By keeping the junction temperature ($T_j$) of electronic components within safe limits, it prevents thermal throttling and hardware failure. * **maxiFLOW™ Geometry:** The fins are tapered and spread out to maximize airflow intake and reduce pressure drop, which is critical in densely packed server racks or networking equipment. --- ### 3. Mounting and Interface The "C1" in the part number indicates the specific mounting and thermal interface configuration: 1. **pushPIN™ Attachment:** Instead of messy adhesives, this part uses a spring-loaded brass pin mechanism. This provides constant, even pressure across the chip surface, improving thermal conductivity. 2. **Pre-applied TIM:** The part comes with **T766 thermal interface material** pre-applied to the base. This eliminates the need for manual thermal paste application and ensures a bubble-free contact between the chip and the heat sink. --- ### 4. Comparison with Standard Heat Sinks Unlike standard extruded heat sinks, the ATS-55300D-C1-R0 is engineered for **forced convection**. * **High Fin Density:** Designed for systems with active fans. * **Directional Airflow:** The fin structure is optimized for linear airflow paths.
