AA4040LSURCKT-AMT

Overview

The Kingbright AA4040LSURCKT-AMT is a single-color red surface-mount LED in a PLCC-2 package. It emits at a wavelength of 645 nm with a typical forward voltage of 1.75 V and a rated forward current of 2 mA. The component features a water-clear lens with a millicandela rating of 43 mcd. Physical dimensions include a 4.00 mm lens size and a rectangular flat-top style.

Feature Summary

• Designed for low current applications to minimize power consumption while maintaining luminous efficacy.
• Constructed using AlGaInP LED chip technology for reliable performance.
• Compliant with RoHS standards and halogen-free construction.

Applications

• Low-power electronic device indicators
• Portable consumer electronics status lights
• Battery-operated instrument panels

Procurement Notes

Verify the specific suffix 'KT-AMT' against official Kingbright documentation to confirm tape-and-reel packaging and moisture sensitivity level (MSL) classification. Ensure the 2 mA forward current rating aligns with system design requirements, as this differs from standard 20 mA variants within the same series.

Selection Notes

Select this variant specifically for ultra-low power designs requiring 2 mA operation rather than standard intensity levels. Confirm that the 645 nm red emission meets visibility needs. Verify compatibility with SMD assembly processes and check MSL handling requirements before procurement.

Part Context

This component belongs to the Kingbright AA4040 series of high-temperature SMD LEDs. The series offers improved material durability and electrical reliability for dense system designs. It utilizes second-generation SMD LED technology to ensure consistent performance across various operating conditions.

Replacement Considerations

Consider AA4040SURSK or AA4040NC for higher current (20 mA) applications if increased brightness is required. For direct functional substitution, verify exact binning and forward voltage tolerances with the manufacturer's latest datasheet.
