LTST-M140QEKT

LED Indication - Discrete Overview

The LTST-M140QEKT is a single-color surface-mount LED manufactured by LITEON. It emits red light at a wavelength of 624 nm with a viewing angle of 120 degrees. The component features a rectangular, water-clear lens and operates within a temperature range of -40°C to +85°C. Electrical specifications include a forward current of 20 mA and a forward voltage of 2 V, resulting in a power rating of 72 mW. Physical dimensions are 3 mm in length, 1.4 mm in width, and 1.2 mm in height. Optical intensity is rated at 180 mcd.

LED Indication - Discrete Feature Summary

• Top-view configuration with a rectangular lens shape for direct visibility.
• Water-clear lens material ensures high transparency for the emitted red light.
• Designed for surface-mount technology (SMD/SMT) installation on printed circuit boards.

LED Indication - Discrete Applications

• Indicator lights in consumer electronics devices
• Status indicators in automotive instrumentation panels
• Visual signaling in home appliance control interfaces

LED Indication - Discrete Procurement Notes

Verify the specific optical intensity binning requirements against project needs, as datasheets may list varying ranges. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure handling procedures account for moisture sensitivity classification to prevent damage during soldering processes. Cross-reference the exact part number suffix to confirm packaging type availability.

LED Indication - Discrete Selection Notes

Select this component when a standard red indicator with a top-view orientation is required. The 120-degree viewing angle provides broad visibility for panel-mounted applications. Consider the 2V forward voltage drop when designing the driving circuit to ensure proper current limiting. The compact PLCC-2 form factor suits space-constrained designs requiring reliable visual feedback.
