Notes)

・The half-life of the optical output at 25℃ is over 3,000hrs at the above If condition.

・Recommended If at 75℃ is 5mA. The half-life under such condition is over 1,000hrs.

・The half-life of the LED is inversely proportional to the square of the operating current.

（The If-Ta curve is also shown in sheet 1.）

Notes）

・Peak wavelength 1 and 2 refers to emissions from the active layer and the substrate,

respectively. White color is obtained by mixing these two light emissions.

・Rank S type employs optical diffuser inside epoxy lens.

・If-Vf, Po-If, and Po-Ta characteristics of a typical white LED is shown in sheet 2.

・A typical Viewing Angle data is shown in Sheet 3.
