APT1608QBC/D

Overview

The APT1608QBC/D is a single-color blue surface-mount LED manufactured by Kingbright. It operates at a peak wavelength of 470 nm with a water-clear rectangular lens. The component features a 0603 (1.6 mm x 0.8 mm) footprint and a height of 0.75 mm. Key electrical parameters include a forward voltage of 3.3 V, a maximum forward current of 20 mA, and a power rating of 120 mW. It delivers an optical intensity of 100 mcd with a viewing angle of 120 degrees. The device supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Emits blue light at a 470 nm wavelength through a water-clear rectangular lens.
• Designed for surface-mount technology with a compact 0603 package profile.
• Provides high luminous intensity of 100 mcd with a wide 120-degree viewing angle.

Applications

• Indicator lights in electronic devices
• Backlighting for displays and keypads
• Status indication in consumer electronics

Procurement Notes

Verify the specific part number suffix against official Kingbright documentation to ensure correct binning and optical characteristics. Confirm moisture sensitivity level handling requirements during storage and reflow soldering processes. Check for RoHS compliance status in the latest datasheet revision. Ensure ordering quantities align with standard reel or cut-tape packaging options provided by distributors.

Selection Notes

Select this component when a standard blue indicator with moderate brightness is required in space-constrained designs. Compare the 100 mcd intensity against alternatives like the APG1608QBC/D if lower brightness suffices. Consider the 0.75 mm height relative to board clearance constraints. Evaluate thermal management needs given the 120 mW power rating and 20 mA forward current limits.

Part Context

This component belongs to the Kingbright APT1608 series of single-color LEDs. The series includes various wavelengths and intensities within the 0603 form factor. Related parts include infrared variants like APT1608F3C and low-current blue versions like APT1608LVBC/D. The series is designed for general-purpose illumination and indication applications requiring reliable SMD performance.

Replacement Considerations

APG1608QBC/D offers similar specifications but with 70 mcd intensity. APT1608LVBC/D provides lower current operation at 2 mA with 24 mcd intensity. KPH-1608QBC-D is a variant with a 465 nm wavelength and 4 V forward voltage. Verify pinout compatibility and mechanical dimensions before substitution.
