Discrete LED indication is one of the most commonly used forms of status indication today. When it comes to LED application, the HLMP-D401 LED is one of the most reliable, cost-effective, and versatile options available. This LED is capable of producing intense, consistent and long-lasting illumination, making it ideal for a host of applications including automotive and industrial signaling. To begin with, the HLMP-D401 LED has a forward voltage of 3.2V, making it suitable for use in common automotive circuits. Additionally, the LED is rated for use in high-density ambient light areas and its small size makes it ideal for tight spaces. Moreover, the LED has an operating temperature range of between -40°C and +85°C, allowing for highly reliable operation in extreme temperatures. With its tolerance to pressure, water, and shock, the LED also has a long in-service life.When it comes to the light itself, the HLMP-D401 features a bright red light with a maximum output of 25,000 millcd. This output can be maintained even at a 10MA current draw, which is excellent for mid-power applications. The LED also benefits from a total viewing angle of 25°, producing a wide and highly visible beam.When it comes to the HLMP-D401’s working principle, it is quite straightforward. When a voltage is supplied, electrons in the forward biased junction of semiconductor material gain energy and move toward the anode. As a result, photons of light are emitted, producing the visible red light.Overall, the HLMP-D401 LED is one of the most reliable, cost-effective, and versatile options for discrete LED indication. It is highly capable of producing intense, consistent, and long-lasting illumination, making it an ideal choice for a vast range of applications. Its small size, wide viewing angle, and forward voltage of 3.2V mean it is suitable for both mid and high-power applications, maximizing its overall versatility.
