40 mm Square x 5 mm High Alpha Heat Sink – 12.7 °C/W

Regular Price: $6.30 /ea

The LPD40-5B Alpha heat sink offers a natural convection thermal resistance rating of 12.7 °C/W within a 40mm square footprint. The elliptical shaped, aerodynamic fins are set in a sparse pattern which makes it easier for air to efficiently flow through the heat sink, making this cooler an ideal choice for either passively or actively cooling high power LEDs.
