Triple Digit Numeric Displays Electrical Optical Characteristics at Ta=25℃
| Parameters | Symbol | Min. | Typ. | Max. | Unit | Test Condition |
| Luminous Intensity | Iv | 40.0 | 50.0 | --- | mcd | IF=20mA (Note 1) |
| Luminous Intensity Matching Ratio (Segment To Segment) | Iv-m | --- | --- | 2:1 | IF=10mA | |
| Peak Emission Wavelength | λp | --- | 640 | --- | nm | IF=20mA |
| Dominant Wavelength | λd | --- | 630 | --- | nm | IF=20mA (Note 2) |
| Spectral Line Half-Width | △λ | --- | 20 | --- | nm | IF=20mA |
| Forward Voltage | VF | --- | 1.80 | 2.40 | V | IF=20mA |

Notes:
1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE
eye-response curve.
2. The dominant wavelength (λd) is derived from the CIE chromaticity diagram and represents the single
wavelength which defines the color of the device.
