Product Overview
5mm through-hole LED emitting yellow light through a water clear (transparent) lens. The clear lens focuses output into a visible beam rather than scattering it, making this well suited for indicator and point-light applications. Breadboard and PCB compatible. Requires DC power, correct polarity, and a current-limiting resistor in series.

Frequently Asked Questions
Do I need a resistor to use this LED?
Yes. A current-limiting resistor in series is required. Connecting directly to a power supply without one will burn out the LED immediately. Calculate resistor value using your supply voltage, the LED forward voltage (typically 1.8V-2.2V for yellow), and a target current around 20mA - but verify Vf and If against a datasheet for your exact batch before use.
What are the exact forward voltage and current specs?
Not confirmed for this specific unit. Typical 5mm yellow LEDs run 1.8V-2.2V forward voltage at 20mA forward current, but these values can vary by manufacturer. Verify against a datasheet before use in current-sensitive designs.
Is this compatible with a breadboard?
Yes. The standard 5mm through-hole package fits standard breadboard spacing and PCB through-hole pads without modification.
Is the lens diffused or clear?
Water clear - the dome is transparent, not frosted. This produces a more focused output compared to diffused LEDs of the same size.
Yellow LEDs from the through-hole era have a certain no-nonsense charm - point them at the right spot, add a resistor, and they just work. Wherever this one ends up, it will do exactly what it was made to do.
