Product Overview
At IF=350 mA and Ta=25°C, the LED is specified for 100-130 lm luminous flux, 6000-7500 K color temperature, and 2.8-3.4 V forward voltage. The maximum continuous forward current is 350 mA at Ta=25°C, with 500 mA peak forward current allowed for pulse width <=0.1 ms and duty <=1/10. The viewing angle is 120 deg at IF=150 mA and Ta=25°C.
Assembly data includes lead and lead-free reflow profiles, a maximum of two reflow soldering cycles, and hand soldering limits for repair or rework. Storage guidance includes unopened storage at <=30°C and <60% RH for up to one year, opened storage at <=30°C and <40% RH with soldering within 168 hours, and baking at 60±5°C for 24 hours if required. Typical use cases include white LED lighting modules, cool-white indicator boards, SMD PCB assemblies, and moisture-controlled LED production workflows.
