PACKAGE DIMENSIONS

FEATURES

• Low power consumption

• Uniform lighting across entire bar

NOTE:

1. Dimensions are in inches (mm).

2. Lead spacing is measured where the leads emerge from
the package.

3. Protruded resin under the flange is 1.5mm (0.059”) max.

4. Tolerance is +/-0.12” (0.3mm) unless otherwise noted.
