APTB1612LSURKSYKC

Overview

The Kingbright APTB1612LSURKSYKC is a bi-color surface-mount LED in the HeliColour series, housed in a compact 1612 (1.6 x 1.25 mm) package with four pins. It features independent red and yellow emitters within a single water-clear dome lens. The device operates at a low forward current of 2 mA, with forward voltages of 1.75 V for red and 1.85 V for yellow. It delivers an optical intensity of 50 mcd for both colors at wavelengths of 630 nm and 590 nm respectively. Rated for power dissipation of 75 mW per color, it functions reliably between -40°C and +85°C.

Feature Summary

• Dual-emitter bi-color configuration enabling simultaneous or independent red and yellow illumination
• Ultra-compact 1.6 x 1.25 mm footprint designed for high-density circuit board layouts
• Water-clear dome lens provides consistent light transmission and visual appearance
• Low-power operation optimized for battery-sensitive portable electronic applications

Applications

• Status indication on compact consumer electronics
• Multi-state signaling in medical devices
• Indicator lights for smart home appliances
• Visual alerts in wearable technology

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Kingbright documentation. Confirm RoHS compliance status through certified datasheets prior to integration. Ensure handling procedures account for moisture sensitivity classification to prevent damage during soldering. Validate electrical parameters against specific application requirements before final procurement decisions.

Selection Notes

Select this component when space constraints require a dual-color indicator in a minimal footprint. The low forward current specification makes it suitable for energy-efficient designs where power consumption is critical. Verify that the required viewing angle and luminous intensity meet visibility standards for the intended enclosure. Consider thermal management capabilities if operating near maximum temperature limits.

Part Context

This component belongs to Kingbright's HeliColour series, which specializes in multi-color LEDs for advanced indication needs. The 1612 package size represents a balance between visibility and board real estate efficiency. As a bi-color device, it offers design flexibility compared to single-color alternatives while maintaining standard SMD mounting compatibility.

Replacement Considerations

APTB1612LSURKZGKC serves as a confirmed substitute variant within the same family.
