DESCRIPTION

This device has been designed to meet the increasing demand for white SMD LED.

The package of the VLMW33. is the PLCC-2.

It consists of a lead frame which is embedded in a white thermoplast. The reflector inside this package is filled with a mixture of epoxy and TAG phosphor.

The TAG phosphor converts the blue emission partially to yellow, which mixes with the remaining blue to give white.

APPLICATIONS

•Automotive: Backlighting in dashboards and switches

•Telecommunication: Indicator and backlighting in telephone and fax

•Backlighting for audio and video equipment

•Backlighting in office equipment

•Indoor and outdoor message boards

•Flat backlight for LCDs, switches and symbols

•Illumination purposes, alternative to incandescent lamps

•General use

Note:

Only one group will be shipped on each reel (there will be no mixing of two groups on each reel).

In order to ensure availability, single brightness groups will not be orderable.

In a similar manner for colors where wavelength groups are measured and binned, single wavelength groups will be shipped on any one reel.

In order to ensure availability, single wavelength groups will not be orderable.
