11-21/R6C-AR2S2B/3T

Overview

The Everlight 11-21/R6C-AR2S2B/3T is a single-color surface-mount LED designed for indicator applications. It features a brilliant red lens with a water-clear finish and emits light at a peak wavelength of 632 nm. The component utilizes a round, through-hole compatible footprint style but is specified for surface mount installation. Key electrical parameters include a maximum forward current of 25 mA and a typical forward voltage of 2.0 V at 20 mA. Optical performance specifies a nominal luminous intensity of 212.5 mcd at 20 mA with a viewing angle of 60 degrees. The device operates within a temperature range of -40°C to +85°C and has a total height of 1.5 mm.

Feature Summary

• High-intensity red emission suitable for clear visual indication
• Water-clear lens design for optimized light transmission
• Robust thermal stability across extended industrial temperature ranges

Applications

• Status indicators in consumer electronics
• Power status displays in industrial control panels
• Signal lights in automotive instrumentation

Procurement Notes

Verify the suffix '3T' against official Everlight documentation to confirm specific tape-and-reel packaging specifications. Ensure that the requested quantity aligns with standard reel sizes to avoid partial reel handling issues. Cross-reference the RoHS compliance status with the latest manufacturer declaration prior to final procurement authorization.

Selection Notes

Select this component when high visibility in red is required for panel-mounted indicators. The 60-degree viewing angle provides adequate coverage for front-facing applications. Consider the 1.5 mm profile height for compatibility with low-profile enclosure designs. Verify thermal management requirements if operating near the upper limit of the specified temperature range.

Part Context

This part belongs to Everlight's standard discrete LED portfolio, characterized by consistent optical output and reliable semiconductor manufacturing processes. The 11-21 series typically denotes a specific package form factor optimized for automated surface-mount assembly. It serves as a fundamental passive-optic component for basic signaling functions in electronic assemblies.

Replacement Considerations

Direct substitutes may include other 0805-sized or similar footprint red LEDs from manufacturers such as Kingbright or Osram, provided they match the 632 nm peak wavelength and 212.5 mcd intensity. Verify mechanical dimensions and soldering thermal profiles before substitution.
