Notes:
(1) Units mounted on a 2.0 x 1.6 x 0.3" thick (5 x 4 x 0.8 cm.) aluminum plate
(2) Units mounted on P.C.B. with 0.5 x 0.5" (12 x 12 mm) copper pads and 0.375" (9.5 mm) lead length
(3) Recommended mounting position is to bolt down on heatsink with silicone thermal compound for maximum heat transfer with #6 screw
