LB-203BL Series

LED displays

High efficiency, three-digit numeric
displays

LB-203BL Series

External Dimensions

The LB-203BL series are small, three-digit numeric
displays with a character height of 6.4mm. These
displays can be combined with appropriate displays in
the two-digit LB-202BL series to form a multi-digit display
with an equal pitch interval between characters.

Features

!

1) Four colors are available : red, orange, yellow, and
green.

2) Common anode and common cathode configurations
are available.

3) Dynamic lighting system to minimize the number of
pins.

4) Equal pitch interval between characters even with
multi-digit display.

5) The package surface is painted black and the
segments are colored the display color.
