5. Select a Resistor to Drive an LED

Neha is designing a 12V LED indicator using a red LED with 2V forward voltage. 

The LED should run at about 22mA for proper brightness. 

Help her select a surface-mount (SMD 1210 package) resistor that limits the current safely and provides reliable long-term operation.
