Product Overview
EL_DSE-0012792-19-217-B7C-ZL2N1B3X-3T-V4 is an EVERLIGHT blue SMD LED based on InGaN chip material and water clear resin. It is supplied in an SMD B package with dimensions defined in millimeters and a stated tolerance of ±0.1 mm unless otherwise specified.
At IF=2 mA and Ta=25°C, the LED is characterized for 14.5 to 36.0 mcd luminous intensity, 468 nm typical peak wavelength, 465.0 to 475.0 nm dominant wavelength, and 25 nm typical spectrum radiation bandwidth. Forward voltage is specified from 2.50 to 2.90 V under the same test condition, with reverse current limited to 50 µA max at VR=5 V.
The device supports compact blue indication and visual signaling functions where a 120 degree typical viewing angle is useful. Handling and assembly limits include 260°C reflow soldering for 10 seconds, a maximum of two reflow cycles, and post-opening storage at 30°C or less and 60% RH or less for 168 hours.
