3mm LED: RED YELLOW

Overview: 3mm LED Red and Yellow

The 3mm LED: RED YELLOW is a compact, reliable light-emitting diode designed for hobbyists, makers, educators, and electronics professionals. Available in vibrant red and yellow colors, these through-hole LEDs deliver bright, energy-efficient light in a miniature package. They are ideal for indicators, status lights, model making, and small decorative lighting projects.

Applications: Where to Use These 3mm LEDs

• DIY Electronics: Status indicators, logic output lights, sensor feedback.
• Arduino and Raspberry Pi Projects: Simple visual feedback, prototypes, and learning kits.
• Model Making and Miniatures: Interior and exterior lighting for scale models and dioramas.
• Panel Indicators and Displays: Power-on, fault, and mode indicators in custom control panels.
• Home Decor and Crafts: Small accent lights, holiday projects, and wearable electronics.

Compatibility and Integration Tips

These 3mm LEDs are designed for easy integration into hobby and professional circuits. Use a current-limiting resistor to protect the LED and ensure reliable operation. Typical resistor calculation example for a 5V supply and a red LED:

• Resistor = (Vsup – Vf) / If = (5V – 2.0V) / 0.02A = 150 ohms (use nearest standard value 150 or 180 ohms)

They plug directly into standard breadboards and solder securely to through-hole PCBs. Polarity matters: the longer lead is the anode (+) and the shorter lead is the cathode (-).

Mounting and Wiring Tips

• Solder using a temperature-controlled iron and avoid prolonged heat on the LED leads.
• Trim leads after soldering to prevent short circuits in compact assemblies.
• For uniform brightness across multiple LEDs, use matched resistors or a proper LED driver when wiring in parallel.

Frequently Asked Questions

Can I use these LEDs with a 3.3V microcontroller?

Yes. For red and yellow LEDs with forward voltages around 2.0V, use an appropriate series resistor to limit current to 20mA or less.

Are these LEDs suitable for outdoor use?

These standard through-hole LEDs are best used in indoor or protected environments. For outdoor installations, consider sealed or waterproof LED options.

The 3mm LED: RED YELLOW is an essential component for projects that need compact, bright, and energy-efficient indicator lighting. Whether you are prototyping with Arduino or building a final product, these LEDs deliver consistent results and long service life.
