DESCRIPTION

This device has been designed to meet the increasing
demand for AlInGaP technology.

The package of the VLME31-series is the PLCC-2.
It consists of a lead frame which is embedded in a

white thermoplast. The reflector inside this package is
filled up with clear epoxy.

APPLICATIONS

• Automotive: Backlighting in dashboards and
switches

• Telecommunication: Indicator and backlighting in
telephone and fax

• Indicator and backlight for audio and video equip­ment

• Indicator and backlight in office equipment

• Flat backlight for LCDs, switches and symbols

• General use

Note:

Luminous intensity is tested at a current pulse duration of 25 ms and
an accuracy of ± 11 %.

The above type numbers represent the order groups which include
only a few brightness groups. 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.
