S4SMS-RJF-CS32QBB1

LED Indication - Discrete Overview

The S4SMS-RJF-CS32QBB1 is a single-color red LED from the Screen Master series by Cree LED. It features a T-1 3/4 (5 mm) through-hole package with an oval lens shape and water-clear transparency. The device emits light at a wavelength of 621 nm. Key electrical parameters include a forward current of 20 mA, a forward voltage of 2.1 V, and a power rating of 130 mW. Optical performance specifies a luminous intensity of 934 mcd and a viewing angle of 100 degrees x 45 degrees. The component operates within a temperature range of -40 C to +95 C and is supplied in an ammo pack.

LED Indication - Discrete Feature Summary

• Oval-shaped radiation pattern designed for wide-angle visibility
• High luminous intensity suitable for clear signage applications
• Through-hole mounting configuration for standard PCB integration

LED Indication - Discrete Applications

• Variable-message signs
• Passenger-information displays
• Public transportation indicator panels

LED Indication - Discrete Procurement Notes

Verify end-of-life status and obsolescence notices directly with the manufacturer before finalizing designs. Confirm RoHS compliance details and specific packaging quantities required for production runs. Ensure that the through-hole footprint matches the T-1 3/4 specification during layout verification. Check for any recent product change notifications affecting optical or electrical characteristics.

LED Indication - Discrete Selection Notes

Select this component when wide viewing angles and high brightness are required for outdoor or high-ambient-light environments. The oval lens geometry provides superior lateral visibility compared to dome lenses. Ensure circuit design accommodates the 2.1 V forward voltage drop at 20 mA. Consider thermal management capabilities given the 130 mW power rating and operating temperature limits.

LED Indication - Discrete Part Context

This part belongs to the Screen Master family of 5-mm oval LEDs, engineered specifically for large-scale display applications. The series emphasizes high luminous efficiency and consistent color performance across manufacturing batches. It serves as a direct replacement for legacy 5-mm oval indicators in modern digital signage infrastructure requiring robust optical output.

LED Indication - Discrete Replacement Considerations

Cross-reference with other Screen Master variants such as C5SMF series for similar form factors. Verify mechanical compatibility with existing tooling and PCB layouts. Ensure optical center height and lens curvature match application requirements for beam alignment.
