Pin-Point LED(AlGaInP) KODENSHI BL15-325 DIMENSIONS (Unit : mm) The BL15-325 is a LED of 650nm wavelength using four elements (AlGaInP). Our original LED processing technology made it possible to increase the electric current density at the emission point. The luminous strength of single light source per unit surface is now more than ten times higher than before. FEATURES •High brightness •The Optical axis match is easy because of red luminance. •Optical design is easy because of the point light of ø150μm APPLICATIONS •Source of light for optical switch , optical fiber , and scanner •Source of light for optical sensor parallel light •Source of light for various , precise measurements MAXIMUM RATINGS Item Reverse voltage Forward current Power dissipation Pulse forward current *1 Operating temp.
