LEDs, or Light Emitting Diodes, come in all shapes and sizes, and can be used in a range of applications from lighting to displays and indicators. A particularly popular form of LED is the WP937SA/3EGW, and it is an efficient and cost effective way to add multiple LEDs to a single circuit board. This product is particularly suited for use in circuit board indicators, arrays, light bars, and bar graphs. The WP937SA/3EGW is a multi-LED module that can be integrated onto a printed circuit board. It is packaged in a 3-pin SOT-26 package, with a footprint of only 1.5mm x 2.0mm. The module includes four red LEDs, which are used to indicate the presence of an illuminated circuit. This unit has an operating temperature rating of up to 85°C, meaning it is well suited to use in high-temperature environments. The working principle of the WP937SA/3EGW is simple and effective. The module utilizes a dual channel current source, which is designed to provide a constant current to the LEDs regardless of varying input voltage and/or temperature conditions. This eliminates the need for two separate “brightness control” circuits that are otherwise required for operation. By simply applying a voltage to the power pins, the LED will be illuminated. The LED’s brightness is determined by the current source control, making it capable of producing a range of intensities from very dim to very bright. The WP937SA/3EGW is designed for use in a variety of circuit board indicators, arrays, light bars, and bar graphs. As an example, it can be used in an 8-segment array to indicate the status of a device. The array can be connected to a logic circuit, which can be used to turn the LEDs on and off. In this way, it can be used to create a simple display for a user interface. Additionally, the WP937SA/3EGW is well suited for applications where multiple LEDs are required, such as in light bars. By connecting multiple units together, a larger area coverage can be achieved. The LEDs can be placed at regular intervals, thus allowing the entire bar to be illuminated with a single voltage application. The intensity of the light is adjustable via a single current setting, making it an efficient and economical solution. The WP937SA/3EGW is a versatile and cost effective solution for a range of LED applications. With its low profile, small footprint, and easy to use working principle, this LED solution is ideal for use in circuit board indicators, arrays, light bars, and bar graphs. Its dual channel current source eliminates the need for two separate circuits, thus reducing the overall cost of the system. With its efficient operation and wide range of applications, the WP937SA/3EGW is a popular choice for many lighting and display needs.
