Product Overview
333-2SUBC_S400-A4 is an EVERLIGHT blue water-clear LED lamp in a through-hole package. The device selection guide identifies InGaN as the chip material, with blue emitted color and water-clear resin. Optical test conditions are specified at IF=20 mA and Ta=25°C, where luminous intensity is rated at 1000 mcd minimum and 2000 mcd typical.
The LED has a 10° typical viewing angle, 468 nm typical peak wavelength, 470 nm typical dominant wavelength, and 20 nm typical spectrum radiation bandwidth. Electrical parameters at IF=20 mA include 3.4 V typical and 4.0 V maximum forward voltage, while reverse current is limited to 50 µA maximum at VR=5 V.
Absolute maximum ratings include 25 mA continuous forward current, 100 mA peak forward current, 5 V reverse voltage, 110 mW power dissipation, and an operating temperature range of -40 to +85°C. Assembly guidance covers 260°C soldering for 5 seconds, 300°C maximum hand soldering tip temperature for 3 seconds, and a 3 mm minimum solder distance from the epoxy bulb.
