Low Current 10 mm Seven Segment Display

Color Type Circuitry
High efficiency red TDSL3150 Common anode
High efficiency red TDSL3160 Common cathode

Description

The TDSL31.0 series are 10 mm character seven
segment low current LED displays in a very compact
package.
The displays are designed for a viewing distance up to
6 meters and available in high efficiency red. The grey
package surface and the evenly lighted untinted
segments provide an optimum on-off contrast.
All displays are categorized in luminous intensity
groups. That allows users to assemble displays with
uniform appearence.
Typical applications include instruments, panel
meters, point-of-sale terminals and household

equipment.
