Its small footprint and tall fin design provide effective thermal dissipation where space is tight.\n\nThe heat sink features three tall fins for increased surface area and comes with pre-applied thermal tape on the bottom for easy attachment. The fins can be filed down if a shorter profile is needed to fit inside an enclosure.\n\nKey Features\n\n\nCompact SMT Design – Fits small surface-mount packages including BGAs, TSSOPs, and QFNs\n\nTall Fin Profile – Three fins maximise heat dissipation in a small footprint\n\nPre-Applied Thermal Tape – Peel-and-stick installation with no additional adhesive needed\n\nTrimmable Height – Fins can be filed down to fit tighter enclosures\n\n\nSpecifications\n\n\nBase Dimensions – 6.75 × 6.75mm (0.26\" × 0.26\")\n\nTotal Height – 10mm (0.39\")\n\nMaterial – Aluminium\n\nThermal Resistance – Approximately 80°C/W\n\nAttachment – Pre-applied thermal tape\n\n\nIdeal For\n\nSurface-mount SoCs and processors\nMotor drivers and linear regulators\nFETs, BGAs, TSSOPs, and QFN packages\nCompact embedded projects with thermal management needs\n\n\nPackage Contents\n\n1× Aluminium SMT Heat Sink (with pre-applied thermal tape)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8432,"title":"Default Title","sku":"AF-1493","price":2.02,"on_sale":false,"in_stock":true,"available_quantity":4,"option1":"Default Title"}]}
