ROHM LD-101VR, LD-101MG, LD-101DU, LD-101YY Datasheet

LD-101 Series

LED displays

Flat displays

LD-101 Series

The LD-101 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.

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.
