599-0540-127F

Overview

The Dialight 599-0540-127F is a single-color yellow LED in the 599 MicroLED series, designed for surface-mount technology. It utilizes a 1206 (3216 metric) rectangular package with dimensions of 3.2 mm length, 1.6 mm width, and 0.8 mm height. The component emits light at a peak wavelength of 589 nm with a viewing angle of 70 degrees. Key electrical parameters include a forward voltage of 3.2 V and a forward current of 30 mA. The lens is colorless and water clear, providing an optical intensity of 190 mcd.

Feature Summary

• Surface-mount design optimized for automated PCB assembly processes
• High-intensity yellow emission suitable for status indication applications
• Water-clear lens configuration ensures maximum light transmission efficiency

Applications

• Panel indicator lights for electronic equipment
• Status indication on control boards
• Visual signaling in industrial machinery

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and moisture sensitivity classification prior to procurement. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, to align with manufacturing requirements. Cross-reference the manufacturer part number against official distributor catalogs to confirm availability and lead times.

Selection Notes

Select this component when a compact 1206 footprint is required for high-brightness yellow indication. Consider the 30 mA forward current requirement for driver circuit design. Evaluate the 70-degree viewing angle against visibility needs. Compare thermal performance and operating temperature range against environmental constraints.

Part Context

This part belongs to the Dialight 599 MicroLED family, which specializes in small-form-factor surface-mount LEDs. The series offers various colors and intensities within standardized packages like 0603 and 1206. These components are engineered for high reliability and consistent optical performance in space-constrained electronic designs.

Replacement Considerations

Direct substitutes may include other 1206 yellow SMD LEDs from manufacturers like Vishay or Lite-On. Verify matching mechanical dimensions, pinout compatibility, and spectral characteristics. Ensure equivalent forward voltage and current ratings to maintain circuit integrity without redesign.
