This release in:

MALVERN, Pa. — November 7, 2007 — Vishay Intertechnology, Inc. (NYSE: VSH) today released a new family of yellow, amber, warm white, and white 1-W power SMD LEDs. The Little Star® VLMK71.., VLMY71.., VLMW71.. and VLMW711.. series offer a low thermal resistance and high luminous intensity for a wide range of applications.

Featuring a SMD power package with a compact 6.0-mm by 6.0-mm footprint and ultra-low profile of 1.5 mm, Vishay.s new Little Star LEDs are among the most robust and light-efficient products on the market. The devices are designed for high current drive, and offer extremely high brightness and a high flux output.

The amber and yellow LEDs each offer two luminous flux options. The white Little Star is available in white VLMW711.. and warm white VLMW71.. versions, with three luminous flux options available for each.

The new LEDs are optimized for backlighting and illumination in automotive and transport, consumer, and general applications. Typical end products include handheld mobile devices, such as mobile phones and PDAs; traffic lights; advertising displays; household appliances, such as ovens and microwaves; and exterior automotive lighting, such as turn and brake lights. Additionally, the white LEDs are ideal for general illumination purposes as an alternative to incandescent lamps.

All devices in the new family offer a 60° half-intensity angle and 120° viewing angle, and are compatible with IR-reflow solder processes. The LEDs are automotive qualified to AEC-Q101 and comply with RoHS 2002/95/EC and WEEE 2002/96/EC. Preconditioned according to JEDEC moisture sensitivity Level 2 standards, the Little Star package is lead (Pb)-free and RoHS-compliant.
