Standard LEDs 3mm Dia.
Standard LED 3mm diameter.
- Forward Voltage (V) : 2 Volts for Red Orange and Yellow
Voltage (V) : 3 Volts for White, Warm White, Bright White, Green and Blue.
- Forward current: 20mA (typical)
The longer of the 2 leads is the Anode, this MUST be connected to the + (Positive) side of the Supply.
The shorter of the 2 leads is the Cathode, this MUST be connected to the - (Negative) side of the Supply.
All LEDs are tested prior to dispatch.
If a supply voltage greater than the rated forward voltage of the LED is to be used,
then a suitable resistor MUST be wired in series with the LED as shown below.
A suitable series resistor is available HERE please refer to the table below:-
|Supply Voltage||LED voltage||Resistance||Current (approximately)||Power rating|
