Overview

The LTST-C191KRKT is a compact surface-mount LED in a standard 0603 (1608 Metric) package, emitting a 631nm red light. It features a water-clear lens and a wide 130-degree viewing angle, making it highly effective for wide-area indication and status signaling. With a low profile of only 0.65mm, it is ideal for height-constrained electronic assemblies.

Why Choose This Part

This LED provides high visibility with a broad 130-degree viewing angle, reducing the need for precise alignment with light pipes. Its standard 0603 footprint and maximum height of 0.65mm ensure compatibility with high-density PCB layouts and automated pick-and-place assembly.

Applications

Status Indicators
Visual feedback for power, connectivity, or error states in handheld and consumer electronics.
Control Panel Backlighting
Illuminating membrane switches and front panels where space is limited.
Symbol Illumination
Uniform lighting for small icons or text on diagnostic equipment and industrial interfaces.

Getting Started

To integrate this LED, calculate the current-limiting resistor based on the typical forward voltage of 2.0V and your target current, usually up to 20mA. Ensure the PCB land pattern follows the 1608 metric standard and observe correct polarity by checking the cathode mark on the bottom of the package.
