Frequently Asked Questions

Q: What colors are available in the 0603 SMD LED 100-pack?

A: These 0603 SMD LEDs are available in white (6000–6500 K cool white), yellow, and blue. Select your preferred color at checkout. Each pack contains 100 diodes of a single selected color.

Q: What voltage and current do these 0603 SMD LEDs require?

A: The forward voltage ranges from 1.8 V to 3.6 V depending on the color selected, with a rated operating current of 20 mA. Always use a current-limiting resistor or appropriate driver circuit to ensure stable operation and maximum lifespan.

Q: Are these LEDs suitable for surface-mount (SMT) soldering?

A: Yes — these are standard 0603 SMD/SMT package diodes designed for surface-mount assembly. They can be soldered with a fine-tip soldering iron, hot-air rework station, or reflow oven, making them compatible with most PCB prototyping and production workflows.

Q: What is the lifespan of these 0603 SMD LED beads?

A: Under normal operating conditions at the rated 20 mA current, these LEDs are rated for up to 100,000 hours of continuous use — making them a highly durable choice for both short-term DIY projects and long-term installations.
