These chip-type LEDs utilize Aluminum Indium GalliumPhosphide (AlInGaP) material technology. The AlInGaPmaterial has a very high luminous efficiency, capable ofproducing high light output over a wide range of drivecurrents. The available colors in this surface mount seriesare 592 nm Amber, 605 nm Orange, 626/631 nm Red forAS AlInGaP.All packages are binned by both color and intensity, exceptfor red color.These ChipLEDs come either in two top emitting packages(HSMx-C170/C190/C191/C150) or in a side emittingpackage (HSMx-C110). The right angle ChipLEDs are suitablefor applications such as LCD backlighting. The topemitting ChipLEDs with wide viewing angle are suitablefor light piping and direct backlighting of keypads andpanels. In order to facilitate pick and place operation,these ChipLEDs are shipped in tape and reel, with 4000units per reel for HSMx-C170/C190/C191 and 3000 unitsper reel for HSMx-C110/C150.These packages are compatible with IR soldering process.
