C4SMF-BJF-CR24Q4T2

Overview

The C4SMF-BJF-CR24Q4T2 is a single-color blue LED from the Screen Master series, manufactured by Cree LED. It features a through-hole radial installation style with a 4 mm oval lens measuring 4.2 mm x 3.1 mm x 6.3 mm. The component emits light at a dominant wavelength of 470 nm with a water-clear lens transparency. Electrical characteristics include a forward voltage of 3.4 V and a forward current of 20 mA, resulting in a power rating of 140 mW. The optical intensity is specified at 811 mcd, with a viewing angle of 100° x 40°. It complies with RoHS standards.

Feature Summary

• High-intensity blue emission optimized for visibility
• Oval lens design provides wide viewing angles
• Through-hole construction for reliable mounting

Applications

• Panel status indicators
• Instrumentation displays
• Control board signaling

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required bin selections for wavelength and intensity. Confirm that the radial lead configuration matches the target PCB footprint dimensions. Check for any recent Product Change Notifications regarding manufacturing site or material updates. Ensure the selected variant meets all applicable environmental compliance requirements for the intended deployment region.

Selection Notes

Select this component when a high-brightness blue indicator is required for direct panel mounting. The oval shape offers distinct visual differentiation compared to standard round LEDs. Consider the 100-degree horizontal viewing angle for broad visibility applications. Verify thermal management capabilities within the assembly, as the 140 mW rating defines operational limits under continuous drive conditions.

Part Context

This part belongs to the Screen Master family of discrete LEDs, designed for high-visibility applications. The C4SMF designation indicates a 4 mm form factor with an oval lens profile. The series is engineered to provide consistent color performance and luminous intensity across production batches, supporting robust industrial and commercial electronic designs.

Replacement Considerations

Cross-reference with other Cree Screen Master blue variants such as C5SMF-BJF-CR24Q4T1 for 5 mm package alternatives. Verify mechanical fitment before substituting with generic 4 mm oval LEDs due to potential lens dimension variances.
