The TDSL31.0 series is a 10 mm character seven segment low current LED display 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 appearance. Typical applications include instruments, panel meters, point-of-sale terminals and household equipment.
The TDSL31.0 series are compact 10 mm character seven‑segment LED displays designed for viewing distances up to 6 m. They are offered in high‑efficiency red with a grey package surface, untinted segments, and categorized luminous intensity for uniform appearance. Typical applications include panel meters, test‑and‑measure equipment, point‑of‑sale terminals, and control units.
Key electrical parameters are provided, such as a reverse voltage of 6 V per segment, a forward current of 15 mA (typical) and a peak forward current of 45 mA. Optical data include a typical luminous intensity of 180 cd per segment at 2 mA and a dominant wavelength of 625 nm. The datasheet also lists power dissipation, temperature ranges, and mechanical dimensions.
