DESCRIPTION

This device has been designed for applications requir­ing narrow brightness and color selection.

The package of this device 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, singe wavelength groups will not be
orderable.
