ROHM LB-402VP, LB-402VF, LB-402MF, LB-402FP, LB-402MP Datasheet

LB-402FP Series

LED displays

High efficiency, two-digit numeric displays

LB-402FP Series

External dimensions

The LB-402FP series were designed to meet
the need for multi-digit numeric displays.
Featuring excellent visibility, these two-digit
LED numeric displays have a character
height of 10mm. A colored cover case is
attached to the surface of the display.

Features

!!!!

1) Two colors are available: red and green.

2) Common anode and common cathode
configurations are available.

3) Each segment has independent pin
connections and making static drive is
possible.

4) Excellent visibility.

Uniform brightness.
Wide view angle.
Character shapes cannot be seen when
not illuminated.
