BÖBLINGEN, Germany, May 16, 2011 — Avago Technologies has announced white high-brightness LEDs in a robust surface-mount-technology package that simplifies manufacturing. The ASMT-UWB1 LEDs are available in a plastic leaded chip carrier-2 package encapsulated in a heat-resistant silicone resin, enabling them to operate in a wide range of environmental conditions with high reliability and long operating life.
The devices deliver high light output for reduced LED count, and they offer tight color uniformity for linear lighting. The high-brightness performance, along with a wide 120° viewing angle, makes the LEDs well-suited for illuminated advertising, backlighting of vending and gaming machines, and for electrical appliances and industrial equipment.
Designers are choosing surface-mount LEDs because of their ease of assembly, compact footprint and manufacturing flexibility, which combine to reduce overall system development costs. The LEDs are packaged in EIA-compliant tape and reels for simplified pick-and-place assembly. Each reel is shipped from a single intensity and tight color bins following the ANSI C78.377-2008 color binning structure to provide uniformity.
The lead-free LEDs also feature a maximum 3.6-V forward voltage, resulting in low power consumption for end applications.
Additional features include compatibility with reflow soldering processes, moisture sensitivity to JEDEC MSL 3, RoHS compliance and electrostatic discharge sensitivity to JEDEC HBM 1000V.
