NOTE:
Dimensions for all drawings are in inches (mm).
DESCRIPTION
These bi-color surface mount chip LEDs are designed to fit industry standard footprint. Small size, low profile and wide viewing
angle make these LEDs ideal for backlighting applications and panel illumination.
FEATURES
• Miniature footprint - 3.2(L) X 2.7(W) X 1.1(H) mm
• Wide viewing angle of 140°
• Water clear optics
• Moisture-proof packaging
• Available in 0.315" (8mm) width tape on 7" (178mm) diameter reel; 2,000 units per reel
