LED COLORS & SPECIFICATIONS
The electrical specifications shown are determined at a basic temperature of 25°C. Polarity marks are on the bottom of the device.
If the source voltage exceeds the rated voltage, a ballast resistor is required. The resistor value can be calculated by using the
formula in the Supplement section. The LED is an integral part of the indicator and not available separately.
