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.
