XWA4LUG147D

LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs

XWA4LUG147D is a type of LED (light emitting diode) circuit board indicator. It is a surface mount device with a bi-color LED that has two separate indicators in one. Designed to fit in a 4.00mm square package, the XWA4LUG147D contains a dual red/green LED and is available in several color combinations. It is particularly suited for circuit board indicators where space is at a premium.

Applications

XWA4LUG147D’s primary use is for circuit board indicators. This type of LED is used in applications such as consumer electronics, office equipment, lighting and automotive electronic equipment. They’re also used in industrial equipment, medical equipment, and telecommunications. Because of its small size and low power consumption, the XWA4LUG147D can be used in applications where space and power are at a premium.

In consumer electronics, XWA4LUG147D can be used as indicators for status and visual feedback for the user. For example, a cell phone may use XWA4LUG147Ds to indicate the strength of the cellular signal, or the battery status. In office equipment, the XWA4LUG147D can be used as indicators for printer status, or to indicate the readiness of electronic documents. In lighting, XWA4LUG147Ds are also used to indicate the various functions of the lighting range, as well as providing feedback to the user.

Working Principle

XWA4LUG147D is a bi-color LED. It has two separate indicators in one small package. The first indicator is a red LED, and the other is green. Each LED is operated by its own separate current. When both LEDs are powered at the same time, they mix and create either amber (a brownish yellow color) or yellow light.

The LEDs are connected in series with a common anode, and each LED can be switched separately. Power is applied to the anode and each LED can be switched on or off. When the red and green LEDs are both switched on, they mix and create the amber or yellow light. When one LED is switched off, only the light from the other LED is emitted.

Summary

XWA4LUG147D is a type of bi-color LED circuit board indicator. It has two separate LEDs in one small package and is particularly suited for circuit board indicators where space is at a premium. Common applications for XWA4LUG147D include consumer electronics, office equipment, lighting, and automotive electronic equipment. They work by having two separate current sources applied to the LED. When both LEDs are powered, they mix and create either amber or yellow light. By switching one LED on or off, it is possible to create either red or green light.
