C4SMA-BGY-CR34Q4S2

Overview

The C4SMA-BGY-CR34Q4S2 is a single-color blue LED from the Screen Master series, featuring a 4-mm oval dome lens. It emits light at a wavelength of 471nm with a luminous intensity of 660 mcd. The component operates at a forward voltage of 2.9V and is designed for high reliability in outdoor environments. It utilizes advanced optical-grade epoxy to ensure superior resistance to high temperatures and moisture, supporting operation up to +105°C.

Feature Summary

• High reliability construction optimized for harsh operating environments
• Advanced optical-grade epoxy providing superior high-temperature and high-moisture resistance
• Blue illumination color with specific radial lead configuration

Applications

• Outdoor signal applications requiring bright sunlight visibility
• Low-power consumption outdoor indicator systems
• Enterprise machine status indication
• Industrial power delivery system monitoring

Procurement Notes

Verify the specific ordering suffix CR34Q4S2 against official Cree LED documentation to confirm exact binning and packaging specifications. Ensure compatibility with automated placement equipment regarding the radial lead form factor. Cross-reference datasheet electrical limits with circuit design requirements to prevent overdriving the 10 mA typical current rating.

Selection Notes

Select this component when high brightness and environmental durability are required for outdoor signage or industrial indicators. The 4-mm oval shape provides distinct visual identification compared to standard round LEDs. Consider the 2.9V forward voltage drop for power supply calculations and verify thermal management capabilities for operation near the +105°C maximum junction temperature limit.

Part Context

This part belongs to the Screen Master 4-mm Oval LED family, which includes red (RGY), green (GGY), and blue (BGY) variants. These LEDs are engineered for large-format video screens and digital signage, offering industry-leading brightness and reliability. The series is trusted for delivering consistent image quality in demanding public display and advertising applications worldwide.

Replacement Considerations

Direct substitutes within the same series include C4SMA-RGY-CR34Q4S2 for red and C4SMA-GGY-CR34Q4S2 for green. Verify that alternative colors meet the specific luminous intensity and viewing angle requirements of the original design without modifying the mechanical footprint or electrical interface.
