How to Use 28mm Leg LED 3MM Yellow Use 2V 20mA
Insert the LED leads through the PCB or panel holes, ensuring the longer lead (anode) goes to the positive side and the shorter lead (cathode) to ground. Solder securely, then add a series resistor calculated by (Supply Voltage – 2 V) ÷ 0.02 A to limit current to 20 mA. After testing, trim excess lead length for a neat finish.

Frequently Asked Questions
How do I calculate the series resistor for these 2V LEDs?
To run at 20 mA, subtract the LED voltage from your supply. For example, with a 5 V source: (5 V – 2 V) ÷ 0.02 A = 150 Ω. Choose a 150 Ω resistor or slightly higher to safely limit current.
Are these LEDs suitable for outdoor use?
The optical-grade epoxy encapsulation provides good resistance to moisture and heat. For prolonged direct outdoor exposure, consider adding silicone potting or a weatherproof enclosure to extend lifespan.
What’s the correct orientation when soldering onto a PCB?
The longer lead is the anode (+) and the shorter lead is the cathode (–). Many LEDs also feature a flat edge on the rim marking the negative side. Observe polarity to ensure proper illumination.
