SURFACE MOUNT LED LAMP

STANDARD BRIGHT 1206

APPLICATIONS

• Keypad backlighting

• Push-button backlighting

• LCD backlighting

DESCRIPTION

These surface mount chip LEDs are designed to ﬁt industry standard footprint. Low proﬁle and wide viewing angle make these

LEDs ideal choices for backlighting applications and panel illumination.

FEATURES

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

• Wide viewing angle of 140°(QTLP650C) or 160°(QTLP650D)

• Water clear (QTLP650C) or diffused (QTLP650D) optics

• Moisture-proof packaging

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

NOTE:

1. Dimensions for all drawings are in inches (mm).

2. Cathode for -2, -3, -4 and B. Anode for -7.
