Frequently Asked Questions
What forward voltage and current ratings must be considered when designing a current-limiting resistor for the SLR343BC4T3F?
The SLR343BC4T3F has a maximum forward voltage of 3.2 V and a maximum forward current of 30 mA. For a 5 V supply, a resistor of approximately 60 ohms limits current to 30 mA, while a 3.3 V supply requires a resistor of about 3 ohms or a constant-current driver to safely operate this blue LED at full brightness.
How does the 470 mcd luminous intensity of the SLR343BC4T3F compare for panel indicator use?
With 470 mcd nominal luminous intensity, the SLR343BC4T3F is bright enough for indoor status panels, front-panel indicators, and equipment displays under typical ambient lighting of 100 to 500 lux. This blue single-LED emission at 30 mA forward current is suitable for on/off indicators, alarm signals, and mode status lights in industrial and consumer electronics enclosures.
Is the SLR343BC4T3F suitable for use in designs requiring RoHS and lead-free compliance?
Yes, the SLR343BC4T3F is RoHS compliant and lead-free (Pb-free), meeting JESD-609 code e1 requirements. This blue LED with 3.2 V forward voltage and 470 mcd intensity is suitable for export to markets requiring RoHS compliance, including EU, China RoHS, and other environmental regulations governing electronic component materials.
