Product Overview
The 27-21_BHC-AP1Q2_3T is an EVERLIGHT blue SMD LED built with an InGaN chip and water-clear resin. It is supplied in the 27-21 SMD package, with package dimensions defined in millimeters and a general drawing tolerance of ±0.1 mm unless otherwise specified.
At Ta=25°C, the device is rated for 25 mA forward current, 5 V reverse voltage, 100 mA peak forward current under duty 1/10 at 1 kHz, and 95 mW power dissipation. Electro-optical characteristics at IF=20 mA include 2.70 V minimum, 3.30 V typical, and 3.70 V maximum forward voltage, with reverse current limited to 50 μA at VR=5 V.
Optical binning covers 28.5 to 72.0 mcd luminous intensity and 464.5 to 476.5 nm dominant wavelength ranges. The device supports reflow assembly up to 260°C max, not more than two reflow cycles, and is packaged as 3000 pieces per reel on 8 mm tape with a 7 inch reel.
