LB-202BL Series

LED displays

High efficiency, two-digit numeric displays

LB-202BL Series

The LB-202BL series are small, two-digit numeric

displays with a character height of 6.4 mm. These

displays can be combined with appropriate displays in

the three-digit LB-203 BL 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) The package surface is painted black and the

segments are colored the display color.
