C4SMB-BGY-CS44Q3S1

Overview

The C4SMB-BGY-CS44Q3S1 is a blue single-color LED from the Screen Master series, manufactured by Cree LED. It features a 4-mm oval lens with a domed top and measures 3.90mm x 3.00mm. The component emits light at a wavelength of 465nm to 470nm. Typical forward voltage is 3.2V, with a maximum rating of 3.8V. The millicandela rating ranges from 1017mcd to 1672mcd. It operates with a forward current of 20mA to 35mA and utilizes an advanced optical-grade epoxy for durability.

Feature Summary

• Constructed with advanced optical-grade epoxy for superior high-temperature and high-moisture resistance
• Features a 4-mm oval lens design with a domed top for optimized light emission
• Engineered specifically for performance in outdoor signal applications

Applications

• Outdoor signal indicators
• High-temperature environment status lights
• Moisture-resistant equipment indication

Procurement Notes

Verify the specific datasheet version when sourcing, as luminous intensity ratings may vary between 1017mcd and 1672mcd depending on the manufacturing batch. Confirm the exact forward voltage requirements against your circuit design, noting the typical 3.2V versus maximum 3.8V specifications. Ensure compatibility with the 4-mm oval footprint during PCB layout validation.

Selection Notes

Select this component when environmental resilience is critical, particularly for outdoor or humid conditions due to its specialized epoxy construction. Consider the 4-mm oval form factor for space-constrained designs requiring a domed lens profile. Evaluate the blue spectrum output (465-470nm) against visibility requirements for the intended application environment.

Part Context

This part belongs to the Screen Master series of LEDs, which are designed for rugged applications. The C4SMB-BGY-CS44Q3S1 variant specifically denotes the blue color option within the 4-mm oval package family. It shares physical dimensions with other variants but differs in optical characteristics and material composition tailored for harsh environments.

Replacement Considerations

Direct substitutes include C4SMB-BGY-CS44Q3C1, which offers similar electrical parameters but may differ slightly in luminous intensity. Verify pinout compatibility and thermal resistance when swapping between S1 and C1 suffixes.
