ROHM LD-603YY, LD-603VR, LD-603MG, LD-603DU Datasheet

LD-603 Series

LED displays

Flat displays

LD-603 Series

The LD-603 series were designed in response to the
need for large, flat displays. These are two-chip, flat
displays with high luminance.

!

Features

1) 6.8×13.8mm planar emission from two chips
connected in series.

2) High luminance, uniform planar emission

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 2 mm 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.
