Press Release Summary:
Surface-mount Models QTLP610C-EB and QTLP611C-EB provide viewing angles of 120° and 130°, respectively. PCB-based, surface-mount Model QTLP601C-EB has 100° viewing angle. All units feature low power consumption, with Vf less than or equal to 3.15V @ 5mA, and narrow forward voltage range of 2.75 to 3.15V. They use DC voltage and do not require auxiliary circuitry. LEDs use InGaN/Sapphire blue, water-clear optics.Original Press Release:
Fairchild Introduces Low-Voltage, Compact, Surface-Mount Blue LEDs for Cell Phones, PDAs, and Other Portable Products
New LEDs are Ideal for Edge Lighting, Back Lighting, and Illumination Applications
San Jose, CA - September 12th, 2002 -Fairchild Semiconductor (NYSE: FCS) today announces the introduction of three new, blue, compact, surface-mount LEDs. The three LEDs feature low voltage operation for low power consumption (Vf < or equal to 3.15V @ 5mA) and a narrow forward voltage range (2.75 to 3.15V) for better color and brightness consistency. The small size and low power consumption make the LEDs ideal for lighting and illumination applications in compact, portable products.
The right angle, surface-mount configuration of the QTLP610C-EB and QTLP611C-EB LEDs makes them ideal for edge lighting LCD displays and other status indicators in cell phones, personal digital assistants (PDA), and other portable communications and electronic devices. Likewise, the low profile, surface-mount configuration of the QTLP601C-EB makes it ideal for back lighting keypads, push-buttons, and LCD displays in the same type of devices.
All three Fairchild LEDs have distinct advantages over conventional cold-cathode fluorescent lamps (CCFL) and electroluminscent lamps (EL) for illumination in compact devices: they are smaller, more reliable, use dc (rather than ac) voltage, and do not require auxiliary circuitry. In addition, low voltage operation and a narrow forward voltage range make the Fairchild LEDs preferable over similar sized, surface-mount blue LEDs for portable devices.
The QTLP610C-EB and QTLP611C-EB are right angle, surface-mount LEDs. The QTLP610C-EB measures 3.0m (long) by 2.0mm (wide) by 1.0mm (high) with a 120° viewing angle, and the QTLP611C-EB measures 2.1mm (long) by 1.0mm (wide) by 0.6mm (high) with a 130° viewing angle. The QTLP601C-EB is a 0603 pcb-based surface-mount package footprint that measures 1.6mm (long) by 0.8mm (wide) by 0.6mm (high) with a 100° viewing angle. All three
components use an InGaN/Sapphire blue LED, water clear optics, and are available in 0.315-inch (8mm) width tape on 7-inch (178mm) diameter reel, with 2,000 units per reel.
Price: US $0.45 each (10,000 pcs)
Availability: Immediate delivery of volume production
