C4SMG-BJF-CR14Q4T1

Overview

The C4SMG-BJF-CR14Q4T1 is a single-color blue LED from the Screen Master series by Cree LED. It features a 4mm oval through-hole package with clear lens transparency. Key electrical parameters include a forward voltage of 3.4 V and a forward current rating of 20 mA, resulting in a power rating of 140 mW. The device emits light at a peak wavelength of 475 nm with a typical luminous intensity of 742 mcd. Physical dimensions are 6.3 mm in height, 4.2 mm in length, and 3.1 mm in width.

Feature Summary

• Emits blue light at a 475 nm peak wavelength for distinct visual indication.
• Utilizes a water-clear lens to maximize light transmission efficiency.
• Designed for through-hole mounting in standard 4mm oval form factors.

Applications

• Panel status indicators
• Equipment front-face signaling
• Control board visual feedback

Procurement Notes

Verify component authenticity against official Cree LED documentation due to obsolete status. Confirm pin compatibility and thermal handling requirements during integration. Check for authorized distributors offering remaining stock or qualified alternatives. Ensure RoHS compliance matches project specifications. Validate datasheet revisions for any parameter updates prior to final design approval.

Selection Notes

Select this component when a specific blue hue at 475 nm is required for panel visibility. Consider the 4mm oval footprint constraints for PCB layout. Evaluate the 3.4 V forward voltage drop against available drive circuitry. Assess the 742 mcd intensity against ambient lighting conditions. Verify that through-hole assembly processes align with manufacturing capabilities.

Part Context

This part belongs to the Screen Master family of LEDs, characterized by high brightness and reliability. It represents a legacy product line from Cree LED, now often associated with Wolfspeed transitions. The 4mm oval shape provides a standardized mechanical interface for industrial enclosures and consumer electronics panels requiring discrete visual signals.
