THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Note (1) Driving LED in reverse direction is suitable for short term application Notes (1) In one packing unit IVmax./IVmin. > 1.6 (2) Forward voltages are tested at a current pulse duration of 1 ms and a tolerance of ± 0.05 V (3) Wavelengths are tested at a current pulse duration of 25 ms and an accuracy of ± 1 nm Note • Luminous intensity is tested at a current pulse duration of 25 ms and an accuracy of ± 11 %. The above type numbers represent the order groups which include only a few brightness groups. Only one group will be shipped on each reel (there will be no mixing of two groups on each reel). In order to ensure availability, single brightness groups will not be orderable. In a similar manner for colors where wavelength groups are measured and binned, single wavelength groups will be shipped in any one reel. In order to ensure availability, single wavelength groups will not be orderable. ABSOLUTE MAXIMUM RATINGS (Tamb = 25 °C, unless otherwise specified) VLRK31..
