Malvern, Pa. Vishay Intertechnology Inc. has released its Little Star family of yellow, amber, warm white, and white 1-W power SMD LEDs. The Little Star family, consisting of the VLMK71.., VLMY71.., VLMW71.. and VLMW711.. series, offers a low thermal resistance and high luminous intensity for a wide range of applications.
Featuring a SMD power package with a compact 6.0 x 6.0-mm footprint and ultra-low profile of 1.5 mm, the Little Star LEDs 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 high-brightness LEDs offer low thermal resistance of 18 K/W and 20 K/W. They also provide high luminous intensity from 7150 mcd to 22400 mcd, and high luminous flux from 21000 mlm to 70000 mlm.
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. The white LEDs are also suitable 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.
Pricing: $0.70 each for the amber and yellow LEDs, and $1.00 to $1.50 each for the warm white and white LEDs for U.S. delivery.
Availability: Samples of the 1-W power SMD LEDs are available now. Production quantities will be available in October 2007, with lead times of six weeks for larger orders.
