ROHM LD-001YY, LD-001MG, LD-001DU, LD-001VR Datasheet

LD-001 Series

LED displays

Flat displays

LD-001 Series

The LD-001 series were designed in
response to the need for medium-sized, flat
displays. These are two-chip, flat displays
with high luminance.

!!!!

Features

1) 4.5 x 9.5 mm planar emission from two
chips connected in series.

2) High luminance, uniform emission.

3) Four colors : red, orange, yellow and
green.

Operation notes

When forming leads, the bend should be at least 2mm from the base of the package. Solder after forming the leads, and
ensure that the inside of the LED is not subjected to mechanical stress while it is hot.
