DESCRIPTION
This low profile, 4-pin LED provides a more uniform and
evenly distributed illumination than existing LED designs. Its
unique optical package enables designers to utilize fewer LEDs
while achieving superior lighting performance.

NOTES:
1. Dimensions for all drawings are in inches (mm).
2. Lead spacing is measured where the leads emerge from
the package.
3. Protruded resin under the flange is 0.059" (1.5 mm) max.
4. All tolerances are ±0.10” (0.25 mm) unless otherwise
specified.
APPLICATIONS
