DESCRIPTION
These solid state indicators offer a variety of color
selection. The High Efficiency Red, Green and Yellow
devices are made with a gallium arsenide phosphide
LED on gallium phosphide substrate. All are encapsulated in
epoxy packages. Their low profile, small size (approximately T-1
size), good viewing angle, and small square leads contribute to
their versatility as all purpose indicators.
