Notes:
1. The digits are categorized for luminance. The luminance category is designated by a letter on the side of the package.
2. The dominant wavelength, λ_d, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the
device.
3. Typical specification for reference only. Do not exceed absolute maximum ratings.
