                      Product Overview

                      The FK 249 SA 220 is a clip-mounting finger-shaped Heat Sink with solder lug, made of aluminium with black passivated finish and tin-plated solder pins. It is suitable for use with TO-220 transistor. The naming finger-shaped is caused by its form which reminds to a hand with opened or spread fingers.
