Product Overview
17-21_GHC-YR1S2_3T is an EVERLIGHT blue SMD LED associated with the datasheet series number 17-21/BHC-AP1Q2/3T. The device uses an InGaN chip and water-clear resin, with a 17-21 SMD, B package defined in millimeters and general drawing tolerance of ±0.1 mm unless otherwise specified.
At Ta=25°C, the LED is rated for 20 mA forward current, 40 mA peak forward current under duty 1/10 at 1 kHz, 5 V reverse voltage for test conditions, and 75 mW power dissipation. Electro-optical characteristics at IF=20 mA include 2.7 V minimum, 3.3 V typical, and 3.7 V maximum forward voltage, plus 50 µA maximum reverse current at VR=5 V.
The optical output is specified as 45.0 to 112.0 mcd luminous intensity with bin ranges P1 through Q2. Dominant wavelength covers 464.5 to 476.5 nm across bins A9 through A12, with 468 nm typical peak wavelength, 25 nm typical spectrum radiation bandwidth, and 140° typical viewing angle. Assembly data includes 8 mm tape on a 7 inch reel, 3000 pieces per reel, and Pb-free reflow guidance with 260°C maximum peak temperature.
