Case temperature of 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, λ d, is derived from the CIE chromaticity diagram and is that single wavelength which defines the color of the device. 4. Typical specification for reference only. Do not exceed absolute maximum ratings. 5. For low current operation the AlGaAs HDS-A series displays are recommended. 6. For low current operation the HER HDS-75 series displays are recommended. 7. For low current operation the Yellow HDS-A8 series displays are recommended. 8. For low current operation the Green HDS-A9 series displays are recommended. 9. The yellow (HDS-74) and Green (HDS-78) displays are categorized for dominant wavelength. The category is designated by a number adjacent to the luminous intensity category letter. 3-7

Soldering/Cleaning Cleaning agents from the ketone family (acetone, methyl ethyl ketone, etc.) and from the chlorinated hydrocarbon family (methylene chloride, trichloroethylene, carbon tetrachloride, etc.) are not recommended for cleaning LED parts. All of these various solvents attack or dissolve the encapsulating epoxies used to form the package of plastic LED parts. For further information on soldering LEDs please refer to Application Note
