5mm LED Dual Colour Red Blue 3 Pin Common Anode Super Bright UK Seller


High Quality Dual 5mm Red and Blue Leds
Common Anode

These are 5mm LEDs with Clear Plastic body. They have 3 pins, the middle pin is common Anode (positive) the other pins are Cathode (negative) one for Red colour and the other Blue.

You can illuminate Red Or Blue Or both.

Red Colour
Vf = 1.8v to 2.0v
If = 20mA
Colour Wavelength = 622nm

Blue Colour
Vf = 3.0v to 3.2v
If = 20mA
Colour Wavelength = 465nm

For any led it is important to apply the correct Vf and If to the led to produce the correct colour light output, otherwise you may see colour output which is not what you may expect. We have taken the measure to test each colour and each batch of leds for correct colour output.
We test the leds by applying 
If =20ma to ensure the colour output is within acceptable tolerances.The If will greatly determine the colour output for any led, but remember not to apply too much current !

should always use a current limiting resisitor when powering an LED,
please see my other buyhere22 listing for suitable resistors.
