Dimensions and Geometry The "77" in the part number indicates the specific size configuration within the series. * **Length/Width:** 25.00 mm x 25.00 mm * **Height:** 20.00 mm (measured from the base) * **Pitch (Fin Spacing):** 1.40 mm * **Mounting Hole Distance:** 30.00 mm (Center to Center) --- ### 3. Component Breakdown The heat sink assembly consists of several distinct electronic cooling parts: 1. **Heat Sink Body:** A square, cross-cut fin design. The cross-cut architecture allows for airflow from any direction, making it ideal for high-density PCBs. 2. **Push Pins:** These are the mechanical fasteners (usually brass or plastic) that secure the sink to the PCB through pre-drilled holes. 3. **Compression Springs:** These sit on the push pins to provide consistent "Down Force," ensuring the heat sink maintains firm contact with the electronic chip. 4. **TIM (Thermal Interface Material):** The **T766** material is pre-applied to the bottom surface. This fills microscopic air gaps between the chip surface and the aluminum to maximize heat transfer. --- ### 4.
