QLSP23YG

Overview

The QLSP23YG is a discrete LED indicator manufactured by Quelighting Corp, designed for surface mount applications in the 0402 (1005 Metric) package. It emits yellow-green light with a dominant wavelength of 570nm and features a viewing angle of 120 degrees. The component operates with a typical forward voltage of 2.05V at a test current of 20mA.

Feature Summary

• Top-view configuration within a compact 0402 surface-mount package
• Yellow-green emission spectrum centered at 570nm
• Wide 120-degree viewing angle for enhanced visibility

Applications

• Discrete status indication on electronic circuit boards
• Visual signaling in industrial control panels
• Component-level status monitoring in consumer electronics

Procurement Notes

Verify manufacturer part number accuracy against official Quelighting Corp documentation before procurement. Confirm package dimensions and pin configuration match design requirements. Ensure storage conditions comply with moisture sensitivity level specifications to prevent soldering defects during assembly.

Selection Notes

Select this component when a low-profile surface-mount indicator is required for space-constrained designs. Consider the 120-degree viewing angle for visibility needs and the 2.05V forward voltage for compatibility with standard logic levels. Validate thermal management requirements for continuous operation at specified currents.

Part Context

QLSP23YG belongs to Quelighting Corp's discrete LED indicator series, focusing on small-form-factor components for modern electronics manufacturing. The 0402 package size supports high-density PCB layouts common in portable devices and compact industrial equipment.

Replacement Considerations

Consult official distributor databases for cross-reference data. Verify electrical parameters and physical dimensions of potential substitutes to ensure mechanical fit and functional equivalence without modifying existing circuit designs.
