LTST-C19HE1WT

LED Indication - Discrete Overview

The LTST-C19HE1WT is a multi-color RGB LED manufactured by Lite-On Inc. It features a surface-mount 0606 (1.6mm x 1.6mm) package with a height of 0.34 mm. The component emits red light at 624 nm, green at 525 nm, and blue at 470 nm. It utilizes a diffused colorless rectangular lens providing a 130-degree viewing angle. Electrical parameters include a forward current of 20 mA, with forward voltages of 2.4 V for red and 3.9 V for both green and blue channels. Power ratings are specified as 75 mW for the red channel and 80 mW for the green and blue channels. Light intensities are rated at 180 mcd for red and blue, and 450 mcd for green. The device operates within a temperature range of -20 C to +80 C.

LED Indication - Discrete Feature Summary

• Integrates three distinct semiconductor chips for red, green, and blue emission within a single compact surface-mount package.
• Utilizes a diffused lens design to provide uniform light distribution across a wide 130-degree viewing angle.
• Constructed with a low-profile rectangular housing suitable for automated surface-mount assembly processes.

LED Indication - Discrete Applications
