LEDs are common elements of many everyday items, and are used to indicate the operating condition or inform users of the device’s status. Arrays of LEDs can display messages and provide visual feedback to the user. Among the LED components are circuit board indicators, arrays, light bars, and bar graphs.

The A2703B/SUR/S530-A3 is a bi-color 4-pin LED that has two distinct watts in one housing. This makes possible one device to operate in different color under different power state. In applications that require the most efficient use of board space and cost effective design, bi-color LED devices like the A2703B/SUR/S530-A3 offer a versatile solution.

The A2703B/SUR/S530-A3 features one red and one green elements in one package. Both elements have its own anode, cathode, and current control pins. The anodes are made of copper-plated steel, while the cathodes are made of gold-plated copper. Both elements are sealed in epoxy resin and have an InGaN (Indium Gallium Nitride)-based chip. The chip is unique to this LED and allows for the bi-color effect.

The A2703B/SUR/S530-A3 is ideal for applications that require two different color indicators. It can be used in appliance, automotive, and desktop systems, as well as in industrial lighting. The device can also be used for applications that require two separate color states: red for warning or alarm, and green for normal operations.

The working principle of the A2703B/SUR/S530-A3 is based on current control. By adjusting the amount of current that flows in the separate current control pins of the LED, the brightness and color of the output can be adjusted. To adjust the brightness of the red element, the amount of current that flows in the red current control pin is adjusted; to adjust the brightness of the green element, the amount of current that flows in the green current control pin is adjusted.

In summary, the A2703B/SUR/S530-A3 is a circuit board indicator that can be used to indicate the status of a system or device. It is a bi-color LED that is sealed in epoxy resin and features two layers of Indium Gallium Nitride on top of each other. The working principle is based on current control, enabling the user to adjust the brightness and color of the output by adjusting the amount of current flowing in the respective current control pins. This makes it ideal for wide range of applications that require two different color indicators.
