Technical Specifications The part number encodes specific physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance (Flowing)** | 1.63 °C/W @ 100 LFM | | **Thermal Resistance (Unducted)** | 11.87 °C/W @ Static Air | | **Dimensions (L x W)** | 25mm x 25mm | | **Height** | 25mm | | **Fin Style** | Fine Pitch (Cross-Cut) | --- ### 2. Key Electronic Components & Features #### A. The Fin Design The "46" in the part number indicates a specific fin pattern. This heat sink uses a **cross-cut** or square-pin fin geometry. - **Purpose:** This design allows for multidirectional airflow, meaning it can dissipate heat effectively regardless of which way the fan is blowing across the board. - **Efficiency:** The high fin density increases the surface area for heat exchange without significantly increasing the footprint. #### B. pushPIN™ Attachment Mechanism Unlike adhesive tapes or simple clips, the pushPIN™ system uses a specific hardware set: - **Springs:** Provides consistent pressure (clamping force) on the processor/chip to ensure optimal thermal interface material (TIM) performance. - **Push Pins:** Nylon or plastic pins that snap into pre-drilled holes in the PCB, ensuring the heat sink does not shift during vibration or shipping. #### C. Blue Anodized Finish The surface is treated with a blue anodized coating. - **Function:** Beyond aesthetics, anodization increases the emissivity of the aluminum surface, slightly improving radiant heat transfer and providing electrical insulation/corrosion resistance. --- ### 3. Applications This part is typically found in: 1. **Telecommunications:** Cooling high-speed data chips. 2. **Embedded Systems:** Small form-factor motherboards. 3. **Power Electronics:** Managing heat in MOSFETs or voltage regulators. 4. **AI/Compute:** Localized cooling for secondary controllers on GPU or Server boards. ---
