Key Technical Specifications | Parameter | Value / Description | | :--- | :--- | | **Component Type** | Push-Pin Heat Sink (Straight Fin) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) with Compression Spring | | **Thermal Resistance** | 6.77° C/W @ 100 LFM (Linear Feet per Minute) | | **Dimensions** | 45.00mm x 45.00mm | | **Height** | 30.00mm | --- ### 2. Design and Construction #### Thermal Interface Material (TIM) The "C3" suffix in the part number indicates the presence of a **Phase Change Material (PCM)**. This is a pre-applied thermal pad that melts and fills microscopic air gaps between the heat sink and the chip surface once the operating temperature is reached, ensuring maximum heat transfer efficiency. #### Attachment Mechanism (Push-Pin) The "R0" designation refers to the mounting hardware. This model uses a **Plastic Push-Pin** system: * **Ease of Assembly:** Allows for quick installation without the need for tools. * **Constant Pressure:** The integrated springs ensure consistent contact pressure between the heat sink and the component, which prevents damage and maintains thermal performance. #### Fin Geometry It utilizes a **Straight Fin** design. This is optimized for systems with a clear, directional airflow (unidirectional). The vertical fins allow air to pass through the length of the heat sink, carrying heat away via convection. --- ### 3. Electronic Applications This part is typically found in the following environments: * **Telecommunications:** Cooling high-speed processors in routers and switches. * **Computing:** Heat dissipation for chipsets, GPUs, or power-dense FPGAs. * **Industrial:** Protection of power modules in automated control systems. --- ### 4. Thermal Performance Comparison The effectiveness of this heat sink depends heavily on the airflow (LFM) provided by the system fans: | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (Natural/Low) | 6.77 | | 300 (Moderate) | 2.50 | | 500 (High) | 1.80 |
