DESCRIPTION

These surface mount chip LEDs are designed to fit industry standard footprint. They are reverse mountable and designed to emit
light through a small cut-out hole in the PC board.

FEATURES

• Small footprint - 3.2(L) X 1.6(W) X 1.1(H) mm

• Wide viewing angle of 130°

• Water clear optics

• Moisture-proof packaging

• Available in 0.315" (8mm) width tape on 7" (178mm) diameter reel; 2,000 units per reel
