Trusted by engineers for its low cost, ease of use, and excellent thermal performance in a tiny footprint.\n\nThe heat sink features four round fins for increased surface area and can be attached using thermal tape or a small amount of thermal paste (not included). 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\nFour Round Fins – Maximise heat dissipation in a minimal footprint\n\nLow Thermal Resistance – Approximately 70°C/W in still air\n\nTrimmable Height – Fins can be filed down to fit tighter enclosures\n\n\nSpecifications\n\n\nBase Dimensions – 6.7 × 6.7mm (0.27\" × 0.27\")\n\nTotal Height – 7.6mm (0.3\")\n\nMaterial – Aluminium\n\nThermal Resistance – Approximately 70°C/W (still air)\n\nManufacturer – Cool Innovations\n\n\nIdeal For\n\nSurface-mount SoCs and processors\nMotor drivers and voltage regulators\nBGAs, TSSOPs, and QFN packages\nCompact embedded projects with thermal management needs\n\n\n\nNote: Thermal tape or thermal paste is not included. You will need to supply your own adhesive thermal interface material.\n\n\nPackage Contents\n\n1× Aluminium SMT Heat Sink\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6859,"title":"Default Title","sku":"AF-1043","price":4.0,"compare_at_price":7.19,"on_sale":true,"in_stock":true,"available_quantity":6,"option1":"Default Title"}]}
