Notes:
1. Units case mounted on 14x14x0.15cm thick Al plate heatsink
2. Units mounted in free air, no heatsink on P.C.B., 0.5 x 0.5" (13 x 13 mm) copper pads, 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 screws
