HLMP-EG15-QT000

Overview

The HLMP-EG15-QT000 is a single-color red LED from the HLMP-E series, manufactured by Broadcom Limited. It features a T-1 3/4 (5 mm) through-hole package with a water-clear dome lens. The device emits light at a peak wavelength of 626 nm and offers a viewing angle of 15 degrees. Key electrical parameters include a forward voltage of 1.9 V and a maximum forward current of 20 mA. The component achieves a luminous intensity of up to 3200 mcd and a total luminous flux of 500 mLm.

Feature Summary

• Provides high-intensity red emission within a narrow 15-degree beam angle for focused visibility.
• Utilizes a standard 5 mm T-1 3/4 through-hole form factor compatible with legacy mounting requirements.
• Features a water-clear non-diffused dome lens to maintain optical clarity and directional output.

Applications

• Panel indicators requiring precise visual signaling
• Instrumentation displays needing high-brightness red illumination
• General-purpose electronic status indication

Procurement Notes

Verify that the specific ordering suffix matches the required binning for luminous intensity and wavelength consistency. Confirm RoHS compliance status as detailed in the official datasheet. Ensure the procurement channel sources genuine components from authorized distributors to guarantee reliability and traceability. Check for any recent product change notifications regarding material or manufacturing updates.

Selection Notes

Select this component when a narrow 15-degree viewing angle is critical for directing light toward a specific target area. Choose the HLMP-EG15-QT000 over wider-angle alternatives to maximize perceived brightness at the point of observation. Consider the 5 mm through-hole package constraints for PCB layout and mechanical housing design. Evaluate the 1.9 V forward voltage drop against the available drive circuitry headroom.

Part Context

This part belongs to the HLMP-E series of single-color LEDs, which are designed for general-purpose indication applications. The series utilizes standard 5 mm packages to ensure broad compatibility with existing electronic assemblies. Broadcom provides this line as a reliable solution for visible light signaling in consumer and industrial electronics.

Replacement Considerations

Direct substitutes within the same series include HLMP-EG15-UX000, which shares identical electrical and mechanical specifications but may differ in packaging quantity. Verify that alternative parts maintain the 15-degree viewing angle and 626 nm wavelength to ensure functional equivalence in optical performance.

FAQ

What is the recommended forward current for continuous operation?

The maximum forward current rating is 20 mA. Operating within this limit ensures optimal lifespan and consistent luminous intensity.

How does the lens shape affect the light distribution?

The dome-shaped lens focuses the emitted light into a narrow 15-degree cone, providing higher intensity in the center compared to flat or diffused lenses.
