LED Indication - Discrete datasheet and documents for LTST-S271KRKT

LTST-S271KRKT

LED Indication - Discrete Overview

The LTST-S271KRKT is a single-color surface-mount LED from Lite-On's LTST series, designed for side-view applications. It emits red light with a peak wavelength of 631 nm and offers a luminous intensity of 54 mcd. The component features a semitube lens shape with water-clear transparency and measures 3 mm in length, 2 mm in width, and 1 mm in height. Electrical characteristics include a forward voltage of 2 V at a forward current of 20 mA, with a maximum power dissipation of 75 mW. It operates within a temperature range of -30 °C to +85 °C and provides a viewing angle of 130 degrees.

LED Indication - Discrete Feature Summary

Side-view emission profile optimized for visibility from lateral angles
Semitube lens design enhances directional light distribution
Compact SMD form factor suitable for space-constrained PCB layouts

LED Indication - Discrete Applications

Status indication on electronic control panels
Backlighting for instrument clusters
Visual signaling in consumer appliances

LED Indication - Discrete Procurement Notes

Verify the specific suffix against official Lite-On documentation to confirm optical and electrical tolerances. Ensure compatibility with moisture sensitivity levels during storage and reflow processes. Cross-reference datasheet parameters for forward voltage and luminous intensity binning requirements before integration into final assembly specifications.

LED Indication - Discrete Selection Notes

Select this component when a side-emitting red LED is required for panel indicators. The 130-degree viewing angle ensures broad visibility compared to top-emitting variants. Confirm that the 2 mm x 1 mm footprint aligns with the target PCB land pattern. Evaluate thermal management needs given the 75 mW power rating and operating temperature limits.

LED Indication - Discrete Part Context

This part belongs to the LTST series of surface-mount LEDs manufactured by Lite-On. The series includes various colors and package types, such as top-view and side-view configurations. The LTST-S271KRKT specifically addresses the need for compact, high-visibility red indicators in modern electronics where board space is limited.
