| LED Infrared LED L7866 Peak emission wavelength: 1.3 m L7866 is a long wavelength LED using an InGaAs chip. Peak emission occurs at 1.3 m, making L7866 ideal for reference light sources when detecting water content or moisture. Features Applications l Peak emission wavelength: 1.3 m l High radiant output power l Reference light source for moisture meter l Light source for photosensitive material s Absolute maximum ratings (Ta=25 C, unless otherwise noted) Parameter Reverse voltage Forward current Forward current derating rate Pulse forward current Symbol V4 I.
