Description
The Green source color devices are made with Gallium Phosphide
Green Light Emitting Diode.
The High Efficiency Red source color devices are made with
Gallium Arsenide Phosphide on Gallium Phosphide Orange Light
Emitting Diode.
The Yellow source color devices are made with Gallium Arsenide
Phosphide on Gallium Phosphide Yellow Light Emitting Diode.
The Super Bright Red source color devices are made with Gallium
Aluminum Arsenide Red Light Emitting Diode.
Notes:
1. All dimensions are in millimeters (inches).
2. Tolerance is
±
0.25(0.01") unless otherwise noted.
3. Lead spacing is measured where the lead emer-
ge package.
4. Specifications are subjected to change without notice.
