Basic Red 3mm LED Round Top Clear Lens

304RC are the most common 3mm red LED, which is the one of the LED electronic component. Here are the steps to use the LED: 

1. Insert the 3mm red LED into the breadboard, making sure that the longer leg (the anode) is connected to the positive rail and the shorter leg (the cathode) is connected to the negative rail. 

2. Connect one end of the suitable resistor to the same row as the cathode of the LED. 

3. Connect the other end of the resistor to the negative rail of the breadboard. 

4. Connect a jumper wire from the positive rail of the breadboard to the anode of the LED. 

5. Connect another jumper wire from the anode of the LED to the positive terminal of the power source. 

6. Connect a final jumper wire from the negative terminal of the power source to the negative rail of the breadboard. 

7. Turn on the power source and the LED should light up. Note: If the LED does not light up, make sure that the connections are correct and that the resistor value is correct.

Electrical Parameters:

*Luminous intensity is measured by ZWL600.

*λD is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.

Red 3mm LED size: 

*This size are also available in Amber LED, UV LED, Pink LED, IR LED ect.*

For all the through-hole LED Lamps, we will produce it with pure gold wire inside for the circuit connection, high quality epoxy lens to lead the lights, silver plated LED frame to hold the LED chip and connect the polarity. The most important thing is the famous branded chip inside for lighting, which will got the most stable lighting performance for our project. 

There are kinds of application for this 3mm Red LED, some people just use it as LED Indicator, some will use it as the back light project and some will use it for the LED therapy light.
