LEDs (Light Emitting Diodes) are popularly used in many electronic circuits as indicators. In applications where multiple indicators are needed, it makes sense to use devices such as the HLMP-2820-FG000 from Hewlett Packard. This device is composed of many LEDs, arranged in multiple rows, in an array. It is used to indicate the presence of a certain condition in the circuit.

The HLMP-2820-FG000 consists of 28 LEDs arranged in 4 rows of 7. Each of these LEDs is red in color and has a forward voltage rating of 2.2V and a forward current rating of 20mA. The LEDs are all connected in parallel, so they all share the same current. They also share the same positive and negative contacts, as well as the same ground.

When the HLMP-2820-FG000 is connected to a circuit, the current flows through the LEDs and lights them up. Depending on the circuit conditions, some of the LEDs may be lit or all of them may be lit. This can be used to indicate the presence or absence of a certain condition in the circuit, either visually or through a controller.

The HLMP-2820-FG000 is typically used in applications such as circuit board indication, arrays, light bars, and bar graphs. In a circuit board indication application, multiple LEDs are used to indicate the presence or absence of various conditions on the board. A light bar could be used to indicate the status of a system, while bar graphs can be used to indicate the level of a certain parameter.

In general, the HLMP-2820-FG000 LED array is a reliable and cost-effective indicator for many applications. It can be easily wired up to a circuit and requires only minimal current. Its red color makes it easy to see and its multiple LEDs allow it to be used for multiple purposes. It is a great device for those who need an indicator for a circuit board, an array, a light bar, or a bar graph.
