5mm LEDs Wavelength and Color Chart
The longer of the two leads is the positive side (Anode) and the shorter of the leads is the negative side (cathode).
Color 5mm LEDs:-
The color options range from ultra-violet through infrared. Many of the colors offered are available in different output viewing angles, but all have clear lenses unlike other 5mm LEDs that use a colored dome lens to create color.
5mm Clear and Diffused :-
The 5mm lenses for these LEDs effect the light that is given off. We have one option in white that has a frosted lens which gives off a soft light and isn't as bright and sensitive to the eyes. In addition we offer most our color options in clear packages in different beam angles. The beam angles just effect how wide your light is. The smaller degrees will be more of a tight spot and will get wider and wider the higher you go. The color LEDs come in 15, 20, 30 45 and 50 degree angles. The White LEDs come in all these angles as well as 70 degree for a more wider angle.
Powering 5mm LEDs
Connecting these 5mm LEDs directly to a power source will destroy the LED. LEDs cannot limit their own current consumption so another device must be used to do so, usually a resistor or LED driver. These LEDs are typically run at a 20mA current but they can be run up to a max of 30mA. It is ok to use resistors to regulate the current to these, we have plenty ¼ watt resistors, all you need to know is what ohm you want. Use this equation to determine the correct resistor size: Ohms = (Source Voltage – LED Voltage Drop)/Amps.
Static Electricity and Handling LEDs
Like other semiconductor devices, LEDs are static sensitive. Take caution when handling them and make sure you minimize static electricity around the components.
Applications Using 5mm LEDs
These LEDs are best for through hole mounting and in applications where you don't have much space at all or room for heat sink. Some ways they are used in everyday applications:
