Vishay VLMW41XX SMD LEDs

Vishay has expanded the colour binning and ordering options for its VLMW41XX series of sapphire-based, cool white SMD LEDs in the PLCC-2 package.

The devices are available in 14 different colour bins with narrow chromaticity coordinate groups, according to CIE1931. Users can order LEDs comprising four adjacent colour bins.

By offering more narrow colour bins and allowing users to order four adjacent colour groups, the series enables designers to eliminate colour differences in applications including backlighting in motor vehicle dashboards and switches; indicators and backlighting in telecommunications systems, audio and video equipment, white goods and office equipment; and flat backlighting for LCDs, switches and symbols in general use.

Built on InGaN technology, the devices offer a ±60° angle of half-intensity, a high luminous intensity ranging from 180 to 450 mcd and a typical colour temperature of 5500 K, cool white.

The devices are qualified according to AEC-Q101 for motor vehicle applications.
