Product Overview
The 27-21_GHC-YR1S2M_3C is an EVERLIGHT mono-color blue SMD LED associated with datasheet part 27-21/BHC-AN1P2/3C. It uses InGaN chip material and a water-clear resin lens, with an SMD B package designation. The provided text does not make the package dimensions legible, but it notes ±0.1 mm package tolerances.
Electrical and optical ratings are specified at Ta=25°C unless otherwise noted. At IF=20 mA, luminous intensity is 28.5 to 72.0 mcd, forward voltage is 2.70 V minimum, 3.30 V typical, and 3.70 V maximum, peak wavelength is 468 nm typical, and dominant wavelength spans 464.50 to 476.50 nm. The viewing angle is 130° typical.
Assembly data includes 8 mm tape on a 7 inch reel with 3000 pieces per reel. Reflow guidance includes a 260°C maximum Pb-free peak, 10 seconds maximum above 255°C, and two reflow cycles maximum. The LED is applicable to blue status indication, display backlighting segments, panel indicators, and compact SMD lighting layouts.
