C5SMF-BJN-CR0U0451

Overview

The C5SMF-BJN-CR0U0451 is a single-color blue LED from the Screen Master family, manufactured by Cree LED. It utilizes a T-1 3/4 (5 mm) through-hole package with an oval lens measuring 5.1 mm x 3.7 mm. The component emits light at a dominant wavelength of 470 nm with a luminous intensity of 1100 mcd. Electrical characteristics 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 viewing angle is specified as 100 degrees by 40 degrees. Operating temperature ranges from -40 C to +95 C.

Feature Summary

• Features an oval-shaped radiation pattern designed for wide-angle visibility in signage applications.
• Constructed with optical-grade epoxy encapsulation to ensure high resistance to heat and moisture.
• Incorporates UV inhibitors within the resin to maintain stable light output during long-term exposure.

Applications

• Variable-message signs
• Passenger-information signs
• Electronic signs and signals

Procurement Notes

Verify component authenticity against official Cree LED documentation due to potential end-of-life status or supply chain variations. Confirm that the specific ordering suffix matches the required lens tint and packaging format. Cross-reference datasheet revisions to ensure compliance with current RoHS standards and material composition requirements before finalizing procurement orders.

Selection Notes

Select this component when a wide viewing angle is required for outdoor readability. The oval lens shape provides distinct horizontal and vertical beam characteristics suitable for specific sign layouts. Ensure circuit design accommodates the 3.4 V forward voltage drop and 20 mA nominal current to maintain optimal luminous intensity without exceeding thermal limits.

Part Context

This part belongs to the Screen Master C5SMF series, which focuses on high-intensity indicators for public information displays. The series emphasizes durability and optical clarity for harsh environments. The C5SMF-BJN variant specifically denotes the blue color option with standard electrical parameters within the broader oval LED product line offered by Cree LED.
