Blue LEDs shed light on displays
The small size and low power consumption of three compact new surface-mount blue LEDs make them ideal for lighting and illumination applications in compact, portable products
The small size and low power consumption of three compact newsurface-mount blue LEDs make them ideal for lighting andillumination applications in compact, portable products. Thethree LEDs feature low voltage operation for low powerconsumption and a narrow forward voltage range (2.75 to 3.15V)for better colour and brightness consistency.

The right-anglesurface-mount configuration of the QTLP610CEB and QTLP611CEB LEDsmakes them ideal for edge lighting LCDs and other statusindicators in cell phones, PDAs and other portable communicationsand electronic devices.
Likewise, the low profile, surface mountconfiguration of the QTLP601CEB makes it ideal for backlightingkeypads, pushbuttons, and LCD displays in the same type ofdevices.
All three Fairchild LEDs have distinct advantages overconventional cold-cathode fluorescent and electroluminscent lampsfor illumination in compact devices: they are smaller, morereliable, use DC (rather than AC) supplies, and do not requireauxiliary circuitry.
In addition, low-voltage operation and anarrow forward voltage range make the Fairchild LEDs preferableover similar-sized surface-mount blue LEDs for portable devices.The QTLP610CEB and QTLP611CEB are right-angle surface-mount LEDs.The QTLP610CEB measures 3.0 x 2.0 x 1.0mm with a 120-degreeviewing angle, and the QTLP611CEB measures 2.1 x 1.0 x 0.6mm witha 130-degree viewing angle.
The QTLP601CEB is a 0603 PCB-basedsurface-mount package footprint that measures 1.6 x 0.8 x 0.6mmwith a 100-degree viewing angle.
All three components use anInGaN/sapphire blue LED, water-clear optics, and are available in8mm-width tape on 178mm-diameter reel with 2000 units per reel.
