Where: R = Resistor Value (Ohms)
E = Source Voltage (V)
V_F = Forward Voltage (V)
I_F = Forward Current (A)
* Forward Peak Current (Max) I_FM 195 mA
LED circuits are isolated and require an external power source.
Reverse Voltage (Maximum)
V_R 5.0 V
If the source voltage exceeds the rated voltage, a ballast resistor is required.
* Note: Pulse width 0.1msec maximum with a maximum duty cycle ratio of 1/10
