HLMP-Q156 Overview

HLMP-Q156 is one of the most popular and widely used discrete LED indication solutions for a variety of applications. This product works great for signaling both ON/OFF states, and has a wide range of colors from which to choose. This LED indication assembly is available in a TO-92 package, and is compatible with multiple pin-out configurations.

Application Field and Working Principle

HLMP-Q156 is used in a variety of LED indication applications, such as automotive, industrial, and commercial lighting systems. This product is designed to work extremely well in any condition, making it a well-rounded solution for applications where signal reliability and durability are critical.The HLMP-Q156 solution consists of a high efficiency LED in a super bright package and a current limiting resistor. The LED itself is optically efficient, meaning that it produces very little heat while providing optimal signal performance. The resistor limits the current by proportionally limiting the voltage across the LED; this ensures that the LED is not overloaded with too much electricity, which could potentially damage the device.In addition to the two main components, the HLMP-Q156 also includes a built-in reverse polarity protection feature to prevent accidental damage. The reverse polarity protection is achieved with a series of electronic components (transistors, resistors, and capacitors) that limit the voltage going in and out of the LED. This feature makes the product exceptionally safe and reliable for applications where the power source could be subject to large transient spikes and unpredictable current flows.Overall, the combination of the high efficiency LED and reverse polarity protection make the HLMP-Q156 an ideal solution for applications requiring discrete LED indication. The product is easy to install, reliable, and operates in virtually any condition. It is also available in a wide range of colors, making it an ideal choice for applications where aesthetics and visibility are important.
