APPLICATIONS

• Keypad backlighting

• Push-button backlighting

• LCD backlighting

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 • Moisture-proof packaging

• Narrow viewing angle of 20° • Available in 0.315" (8mm) width tape on 7" (178mm) diameter reel;

• Water clear optics 2,000 units per reel
