LEDs are quickly becoming the de facto choice when it comes to circuit board indicators, arrays, light bars, bar graphs, and more. They offer a wide range of colors, require little power, and are extremely versatile. The MR30509MP8B is one such LED that offers a wide range of applications and easy-to-use functionality.

This LED is a common anode dual color LED, which means it has two different colors—in this case, red and green—that can both be lit simultaneously or independently. It is housed in a standard 3050 SMD package, making it compatible with any standard 3050 SMD channels. The LED is capable of illuminating both colors at once, creating an eye catching spectacle that is also highly visible. Additionally, the MR30509MP8B features a wide viewing angle of up to 140°.

The MR30509MP8B can be used for a variety of applications, such as warning or emergency lighting, or as a status or signal indicator. It comes with an internal resistor and is designed to run off a DC supply between 2.8-3.6V, making it suitable for most DC powered projects. It is also RoHS compliant, so it can be used in a range of projects without worry.

The working principle behind the MR30509MP8B is fairly simple. In the simplest terms, it is a two-color LED composed of two different colored diode elements. Each diode element requires a separate power supply, and they can either be combined to create a two-color effect, or operated independently of each other. When combined, the two elements act in a complementary manner; when one element is lit, the other turns off, and vice versa. The resistance inside the LED also helps to regulate the current and protect the diode elements from damage.

In conclusion, the MR30509MP8B is a highly versatile and efficient LED for circuit board indicators, arrays, light bars, bar graphs, and other applications. It is easy to use, has a wide viewing angle, and is RoHS compliant. Combined with its low energy requirements, the MR30509MP8B is an excellent choice for any project that requires LEDs.
