5mm LED Dual Colour Red Olive Green 3 Pin Common Anode UK Seller UK Stock
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 Olive Green.
You can illuminate Red Or Olive Green Or both.
Vf = 1.9v to 2.3v
If = 20mA
Colour Wavelength = 622nm
Olive Green Colour (This is a light pale green)
Vf = 2.0v to 3v
If = 20mA
Colour Wavelength = 571nm
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 !
IMPORTANT: You should always use a current limiting resisitor when powering an LED,
please see my other buyhere22 item for suitable resistors.
