LTST-T680QSWT

LED Indication - Discrete Overview

The LTST-T680QSWT is a single-color surface-mount LED manufactured by Lite-On Inc. It emits yellow light with a peak wavelength of 590 nm and features a diffused lens for wide viewing angles. The component utilizes a PLCC2 (2-SMD) package, measuring 3.20 mm in length, 2.80 mm in width, and up to 2.00 mm in height. It operates at a forward current of 20 mA with a typical forward voltage of 2.1 V.

LED Indication - Discrete Feature Summary

• Diffused lens design provides a 120-degree viewing angle for broad visibility.
• Miniature PLCC2 package optimized for automated PC board assembly.
• Yellow emission suitable for standard indicator applications.

LED Indication - Discrete Applications

• Panel indicators
• Status lights
• Automated PCB assembly

LED Indication - Discrete Procurement Notes

Verify the specific suffix QSWT to confirm the yellow color and diffused lens configuration. Ensure compatibility with RoHS3 standards and MSL level 3 handling requirements during storage and soldering processes.

LED Indication - Discrete Selection Notes

Select this component when a compact yellow indicator with wide dispersion is required. The PLCC2 form factor supports space-sensitive designs. Confirm that the 2.1 V forward voltage aligns with the target circuit drive capabilities.
