Bi Colour LED
Bi Colour Red / Yellow LED 3mm diameter.
- Forward Voltage 2 Volts
- Clear Lens
- Forward current: 20mA (typical)
Connections:
These LEDs are 2 wire dual colour. Basically there are 2 LEDs in the same package wired back to back with the colour changing depending on the polarity of the supply.PLEASE NOTE:
All LEDs are tested prior to dispatch.
If a supply voltage greater than 2 volts is to be used then a suitable series resistor MUST be used.
A suitable series resistor is available HERE please refer to the table below:-
| Supply Voltage | LED voltage | Resistance | Current (approximately) | Power rating |
|---|---|---|---|---|
| 3.3V | 2V | 68 Ohm | 20mA | 0.25W |
| 3V | 15 Ohm | 20mA | 0.25W | |
| 5V | 2V | 150 Ohm | 20mA | 0.25W |
| 3V | 100 Ohm | 20mA | 0.25W | |
| 6V | 2V | 220 Ohm | 20mA | 0.25W |
| 3V | 150 Ohm | 20mA | 0.25W | |
| 9V | 2V | 390 Ohm | 20mA | 0.25W |
| 3V | 330 Ohm | 20mA | 0.25W | |
| 12V | 2V | 510 Ohm | 20mA | 0.5W |
