LEDs slim down for handset backlighting
Avago Technologies has introduced the industry's thinnest surface mount (SMT) light emitting diodes (LEDs) in the smallest industry-standard (0603) footprint available.
Avago Technologies has introduced the industry's thinnest surface mount (SMT) light emitting diodes (LEDs) in the smallest industry-standard (0603) footprint available With an ultrasmall form factor about the size of a pencil tip, these low-power LEDs use high-brightness chips to provide excellent illumination with minimum current consumption

Agilent Technologies has introduced a series of surface-mount LEDs designed and qualified specifically for automobile interior and exterior lighting applications.
Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
These new ChipLED lamps from Avago are available in blue and phosphor white - the colours most widely used by handset manufacturers.
Avago's ultra-thin HSMR-CL25 (blue) and HSMW-CL25 (white) LEDs are ideal for backlighting keypads and status indicators in the thinnest handsets, as well as for office automation devices and consumer electronics.
Moreover, these new top emitting LED packages represent a lower-cost alternative to electroluminescent (EL) backlighting, eliminating the need for high voltages and difficulties with high-frequency electrical noise.
By introducing the world's thinnest top emitting surface mount LEDs in an industry-standard ChipLED package configuration, designers can develop even smaller and thinner mobile handsets, handheld games and other miniature devices.
The Avago HSMR-CL25 is indium gallium nitride (InGaN) blue, with 473nm dominant wavelength and 11.2-45mcd luminous intensity; the HSMW-CL25 is InGaN phosphor white with 28.5-112.5mcd luminous intensity.
(All intensities are typical, measured at 5mA drive current, and all packages use diffused optics).
The top emitting package, with its wide viewing angle, is suitable for direct backlighting or use with light pipes.
Avago's HSMR-CL25 and HSMW-CL25 ultra-thin ChipLEDs are supplied in 8mm tape on 178mm-diameter reels for compatibility with automated manufacturing.
Samples and production quantities are available now through Avago's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
