ELECTRICAL SPECIFICATIONS FOR LED
LED is 5-volt 4-element with resistor The electrical specifications shown are determined at a
basic temperature of 25°C. If the source voltage exceeds
the rated voltage, a ballast resistor is required. The follow-
ing diagram and formula will assist in calculating the value
of the ballast resistor.
