Technical Specifications The following table outlines the physical and thermal characteristics of this specific part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (with Blue Anodized finish) | | **Thermal Resistance** | 2.99°C/W @ 200 LFM | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W)** | 45mm x 45mm | | **Height** | 24.50mm | | **Pressure Drop** | Low (Optimized for high airflow) | --- ### 2. Key Component Features #### A. The maxiFLOW™ Design The "F" in the part number signifies the **maxiFLOW** geometry. Unlike standard square fin heatsinks, this design features a flared fin structure. This increases the surface area for heat dissipation while reducing the resistance to airflow (pressure drop), making it ideal for high-density electronic enclosures. #### B. pushPIN™ Attachment The **-R0** suffix indicates the inclusion of the **pushPIN™** assembly. - **Mechanism:** It uses a flexible spring and a plastic pin that snaps into pre-drilled holes on the PCB. - **Benefit:** This ensures constant and even pressure (Interface Pressure) between the heatsink and the electronic component (CPU/GPU/FPGA), which is critical for efficient heat transfer. #### C. Thermal Interface Material (TIM) The "C2" designation typically refers to the pre-applied thermal interface material. - **Type:** Often a high-performance thermal tape or phase-change material. - **Function:** It fills microscopic air gaps between the component die and the heatsink base to maximize thermal conductivity. --- ### 3. Application Use Cases This part is commonly used to cool high-heat-generating surface-mount devices: * **FPGAs & ASICs:** Used in networking hardware and telecommunications. * **Processors:** Embedded CPUs in industrial computing. * **Power Electronics:** High-power transistors or converters requiring stable temperature regulation.
