Vishay Intertechnology Inc. claims that its series of sapphire-based, high-intensity blue SMD LEDs offer highly efficient InGaN technology at a lower cost than standard InGaN blue LEDs. The VLMB41XX LEDs also feature a high luminous intensity of 45-112mcd.

The six new SMD LEDs in the VLMB41XX series provide illumination for applications including backlighting in automotive dashboards and switches, indicators and backlighting in telecommunications systems, A/V equipment, and office equipment and flat backlighting for LCDs, switches and symbols in general use.

The VLMB41XX devices offer a 60? angle of half intensity and an ESD-withstand voltage up to 2kV, in accordance with JESD22-A114-B. The devices are housed in the EIA- and ICE-standard PLCC-2 package, which consists of a leadframe embedded in a white thermoplast. The reflector inside this package is filled with clear epoxy.

Preconditioned according to JEDEC Level 2a standards, the PLCC-2 package is lead free and RoHS compliant. The devices are CECC compatible with infrared, vapor phase, and wave solder processes to simplify handling. For automatic component insertion, the PLCC-2 package is available in an anti-static 8-mm blister tape in accordance with DIN IEC 40 (CO) 564.

The LEDs are priced at Rs.4.90 (12 cents) per piece and are available for U.S. delivery. Samples and production quantities are available now, with lead times of five weeks for larger orders.
