SMTL4-RYB

LED Indication - Discrete Overview

The SMTL4-RYB is a surface-mount tri-color LED from Bivar, Inc., housed in an industry-standard PLCC-4 package. It integrates three super bright chips (Red, Yellow, Blue) into a single low-profile component with a water-clear lens. Key electrical parameters include a forward current of 20 mA and a viewing angle of 120 degrees. The Red chip operates at 640 nm, the Yellow at 592 nm, and the Blue at 468 nm. This configuration allows for multiple color combinations within a compact footprint suitable for automated assembly processes.

LED Indication - Discrete Feature Summary

• Integrates three distinct semiconductor chips (Red, Yellow, Blue) within a single PLCC-4 package to enable multi-color output.
• Features a water-clear lens design that supports a wide 120-degree viewing angle for enhanced visibility.
• Utilizes a low-profile surface-mount construction compatible with standard SMD/SMT manufacturing equipment.

LED Indication - Discrete Applications

• Status indication on electronic control panels
• Multi-state signaling in industrial automation systems
• Visual feedback components in consumer electronics devices

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version when sourcing, as optical characteristics may vary slightly between production batches. Confirm that the supplier provides RoHS compliance documentation consistent with current environmental regulations. Ensure storage conditions account for moisture sensitivity levels if the component has been exposed to ambient humidity prior to soldering.

LED Indication - Discrete Selection Notes

Select this component when space constraints require a single package to provide multiple distinct color states or complex signaling patterns. The PLCC-4 form factor ensures compatibility with existing PCB footprints designed for similar discrete LEDs. Consider the specific wavelength requirements for each color channel to ensure adequate contrast against the application background.

LED Indication - Discrete Part Context

This part belongs to Bivar's SMTL4 series, which specializes in surface-mount indicator LEDs. The series is characterized by its use of the standard PLCC-4 footprint, facilitating easy integration into high-volume manufacturing lines. The SMTL4-RYB variant specifically addresses applications requiring red, yellow, and blue illumination without occupying separate board real estate for individual diodes.

LED Indication - Discrete Replacement Considerations

Direct replacements must match the PLCC-4 footprint and pinout configuration. Verify that substitute tri-color LEDs offer comparable luminous intensity and viewing angles. Ensure the alternative component supports the same forward current ratings to maintain circuit integrity and brightness levels.
