QBLP601-IW

LED Indication - Discrete Overview

The QBLP601-IW is a white diffused surface-mount LED from QT Brightek, designed for indicator applications. It utilizes a standard 0603 (1608 metric) package with dimensions of 1.60mm length, 0.80mm width, and a maximum height of 0.60mm. The component features a yellow lens with a diffuse transparency and a rectangular lens style with a flat top. Key electrical parameters include a typical forward voltage of 3.2V and a test current of 20mA. It provides an optical intensity of 330mcd with a viewing angle of 140 degrees. The device is compliant with RoHS3 standards and has a Moisture Sensitivity Level (MSL) rating of 3.

LED Indication - Discrete Feature Summary

• Diffused white light emission within a compact 0603 SMD footprint
• High viewing angle of 140 degrees for broad visibility
• Yellow lens material with diffuse transparency to scatter light evenly
• RoHS3 compliant construction suitable for environmentally regulated assemblies

LED Indication - Discrete Applications

• Status indication in consumer electronics
• Power and activity indicators on circuit boards
• Backlighting for small form-factor devices
• Visual signaling in industrial control panels

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging format matches production requirements, such as tape and reel for automated assembly or cut tape for prototyping. Confirm that the 3.2V forward voltage aligns with the target driver circuit design. Check the MSL 3 rating to determine reflow soldering constraints and storage conditions. Ensure the 0603 package dimensions fit within the designated PCB land pattern without mechanical interference.

LED Indication - Discrete Selection Notes

Select this component when a low-profile white indicator is required in a standard 0603 space. The 330mcd intensity offers sufficient visibility for general status signaling. Consider the 140-degree viewing angle if wide-area illumination is necessary. The diffuse lens eliminates hot spots, making it suitable for aesthetic applications where uniform light distribution is prioritized over raw brightness. Verify compatibility with standard lead-free soldering processes due to RoHS3 compliance.

LED Indication - Discrete Part Context

This part belongs to the QBLP601 series of single-color LEDs manufactured by QT Brightek. The series focuses on providing reliable surface-mount solutions for various indicator needs. The QBLP601-IW specifically addresses the demand for white light in compact electronic designs. It shares the same physical footprint and mounting characteristics as other variants in the series, differing primarily in color and lens treatment.

LED Indication - Discrete FAQ

What is the peak wavelength for the white light output?

The provided documentation does not specify a single peak wavelength for the white light; it defines the output by color description and luminous intensity.

Is the lens clear or diffused?

The lens is specified as diffuse, which helps in scattering the light to provide a uniform appearance.
