DESCRIPTION
These surface mount chip LEDs are designed to fit industry standard footprint. The package features a recessed, inner lens that
focuses light output, offering greater luminous intensity for direct viewing.
FEATURES
• Small footprint - 3.0(L) X 1.5(W) X 1.5(H) mm
• Narrow viewing angle of 20°
• Water clear optics
• Moisture-proof packaging
• Available in 0.315" (8mm) width tape on 7" (178mm) diameter reel;
2,000 units per reel
