Product Overview
The 17-21_S2C-AN1P2B_3T is an EVERLIGHT mono-color blue SMD LED. It is built with an InGaN chip and water-clear resin, and it is supplied in an SMD-B package with drawing dimensions specified in millimeters and a ±0.1 mm tolerance unless noted.
At IF=20 mA and Ta=25°C, the LED provides 45.0 to 112.0 mcd luminous intensity, a 468 nm typical peak wavelength, and a 464.5 to 476.5 nm dominant wavelength. The typical viewing angle is 140 degrees, with a 25 nm typical spectrum radiation bandwidth. Forward voltage is specified from 2.7 V to 3.7 V, with 3.3 V typical.
Absolute maximum ratings include 20 mA forward current, 40 mA peak forward current at duty 1/10 and 1 kHz, 5 V reverse voltage, and 75 mW power dissipation. The operating temperature range is -40 to +85°C, and storage is -40 to +90°C.
For assembly, the part supports reflow soldering at 260°C for 10 seconds and hand soldering at 350°C for 3 seconds. Packaging is 8 mm tape on a 7 inch reel with 3000 pieces per reel.
