Notes:
1. Case temperature of the device immediately prior to the intensity measurement is 25° C.
2. The digits are categorized for luminous intensity. The intensity category is designated by a letter on the side of the package.
3. The dominant wavelength, 
d
, is derived from the CIE chromaticity diagram and represents the single wavelength which de nes the color of
the device.
4. Typical speci cation for reference only. Do not exceed absolute maximum ratings.
