Notes:
4. The displays are categorized for luminous intensity with the intensity category designated by a letter on the left hand side of the
package. The luminous intensity minimum and categories are determined by computing the numerical average of the individual dot
intensities.
5. The dominant wavelength is derived from the C.I.E. Chromaticity diagram and is that single wavelength which defines the color of the
device.
6. Typical specification for reference only. Do not exceed absolute maximum ratings.
7. The displays are categorized for dominant wavelength with the category designated by a number adjacent to the intensity category
letter.
