ROHM LD-701YY, LD-701VR, LD-701MG, LD-701DU Datasheet

LD-701 Series

LED displays

Large flat displays

LD-701 Series

The LD-701 series were designed in
response to the need for large, flat displays.
These are three-chip, flat displays with high
luminance.

!!!!

Features

1) Three independent chip elements.

2) Large 4.5 x 19.8 mm emission area.

3) Thin outer casing, multiple units can be
coupled together.

4) Four colors are available: 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.
