Product Overview
LT670LGCT is a pure green surface-mount LED associated with the Para Light Electronics Co., Ltd. datasheet part number LLT670LGCT-BKS. The component uses InGaN dice material and a water clear lens in a PLCC-2, 3528 surface mount package. The datasheet identifies the LED type as fluorescence type, with Pb-free status and RoHS-compliant product version.
At IF=20 mA and Ta=25°C, the device is specified for 1500 to 2500 mcd luminous intensity, 515 to 525 nm dominant wavelength, 515 nm typical peak wavelength, 25 nm typical spectral line half-width, and 120 degree typical viewing angle. Electrical limits include 2.6 to 3.4 V forward voltage at IF=20 mA, 30 mA DC forward current, 100 mA peak forward current at 1/10 duty cycle and 0.1 ms pulse width, and 5 V reverse voltage.
Assembly guidance includes 260°C reflow soldering for 5 seconds, 300°C hand soldering for 3 seconds, and two maximum reflow passes. These parameters suit designs requiring a compact pure green PLCC-2 SMD indicator or display light source.
