Overview
The QLSP23Y is a discrete LED component manufactured by Quelighting Corp, designed for indication applications. It features a yellow light emission with a peak wavelength of 590nm. The device utilizes an SMD package in the 0402 (1005 Metric) footprint, suitable for space-constrained circuit designs. Typical forward voltage is specified at 2.05V, with a standard test current of 20mA. The optical characteristic includes a viewing angle of 120 degrees, providing broad visibility. The lens style is rectangular with a flat top, and the lens dimensions are 0.65mm x 0.55mm.
Feature Summary
- Yellow light emission optimized for visual indication tasks
- Compact 0402 surface-mount package for high-density PCB layouts
- Wide 120-degree viewing angle for enhanced visibility
Applications
- Electronic device status indication
- Panel indicator lights
- Consumer electronics signaling
Procurement Notes
Verify the specific datasheet revision to confirm electrical tolerances and binning classifications before integration. Ensure compatibility with automated pick-and-place equipment due to the small 0402 form factor. Confirm storage conditions and moisture sensitivity level requirements to maintain component reliability during assembly processes.
Selection Notes
Select this component when a low-profile yellow indicator is required for compact consumer or industrial electronics. The 0402 size offers a balance between visibility and board space efficiency compared to larger packages. Consider the 2.05V forward voltage drop for power supply design calculations to ensure proper current limiting resistor selection.
Part Context
Quelighting Corp specializes in LED lighting solutions for various industries, including automotive and horticultural applications. The QLSP23Y belongs to their discrete LED indication series, which provides standardized components for general-purpose signaling needs across different electronic product categories.
Replacement Considerations
QLSP23A is a documented alternative from the same manufacturer, featuring similar physical dimensions but emitting red light instead of yellow. Verify wavelength requirements when substituting to ensure color consistency in the final application.
