  • Features: 100 Ohm Resistors, Tolerance 0.1%5%

Calculations:

• Resistors:

  • Power Supply Voltage Range: 5V

    Forward Voltage: 3.3V

    Desired LED Current: 15mA

    Resistance= (Power Supply V - Forward Voltage)/Desired LED Current

    • R=(5V-3.3V)/(15mA)=113.34 Ohms

    • With 100 Ohm Resistor: I=(5V-3.3V)/100= 17mA Max mA=20mA
