NTE Electronics NTE30157 Data Sheet
NTE30157 thru NTE30160
Discrete RGB LED Indicators
10mm (T−3 1/4) 4−Pin Package Type
Description:
NTEs 10mm RGB LED indicators combine 3 LEDs (1 Red, 1 Green, & 1 Blue) in one convenient,
4−lead package. Available in either common anode or common cathode polarity and clear or diffused
lens types, this one LED can be used for three status indicators or pulse width modulate all three and
get mixed colors!

Creating Different Colors:
With an RGB LED, in addition to being able to produce red, green, and blue light, by configuring the
intensity of each LED, you can produce other colors as well. To achieve a purely blue light, the blue
LED would be set to the highest intensity, while the intensity of both the green and red LEDs would
be set to the lowest. For a white light, all three LEDs would be set to their highest intensity.
In order to produce other colors, you would need to combine all three colors (RGB) using different
intensities. This can be done by using a Pulse Width Modulator (PWM) to adjust the intensity of each
LED. Because the LEDs are set very close together within a single package, our eyes see the result
of the combination of colors, rather than the three colors individually.
