ROHM LD-201YY, LD-201VR, LD-201MG, LD-201DU Datasheet

LD-201 Series

LED displays

Flat displays

LD-201 Series

The LD-201 series were designed in response to the
need for small, flat displays. These are single-chip, flat
displays with high luminance.

!

Features

1) Planar emission from a single chip.

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

3) Long leads are suitable for a wide range of mounting
options.

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.
