Product Overview
The EVERLIGHT 17-21_Y2C-CN1P2B_3T is a blue SMD indicator LED built with an InGaN chip and water-clear resin. It is categorized as an LED and supplied in a 17-21 SMD-B package, with mechanical dimensions defined by the datasheet drawing in millimeters and a general tolerance of ±0.1 mm unless otherwise specified.
At IF=20 mA and Ta=25°C, the device provides 45.0 to 112.0 mcd luminous intensity, a 468 nm typical peak wavelength, and a dominant wavelength range of 464.5 to 476.5 nm. The typical viewing angle is 140°, supporting broad-angle visual indication.
Electrical and handling limits include 20 mA forward current, 40 mA peak forward current at duty 1/10 and 1 kHz, 75 mW power dissipation, and 150 V HBM electrostatic-discharge rating. Assembly guidance includes 260°C for 10 seconds reflow soldering, 350°C for 3 seconds hand soldering, and a maximum of two reflow cycles.
