HT-191USD-5313

LED Indication - Discrete Overview

The HT-191USD-5313 is a surface-mount LED from Harvatek Corporation, housed in a 0603 (1608 Metric) package. It emits ultra-bright red light with a dominant wavelength of 622nm. The component operates at a typical forward voltage of 1.9V and a test current of 20mA. It features a viewing angle of 130 degrees and delivers an intensity of 120mcd. The device is lead-free and RoHS compliant.

LED Indication - Discrete Feature Summary

• Top-emitting design for clear visual indication
• Wide 130-degree viewing angle for broad visibility
• Ultra-bright red output optimized for status signaling

LED Indication - Discrete Applications

• Electronic device status indicators
• Control panel signal lights
• Consumer electronics front panels

LED Indication - Discrete Procurement Notes

Verify the specific suffix -5313 to confirm the 622nm wavelength and 120mcd intensity. Confirm availability as this model may be discontinued; check for active stock or valid substitutes like B1911USD. Ensure the 0603 footprint matches the PCB layout requirements before ordering.

LED Indication - Discrete Selection Notes

Select this component when a compact 0603 form factor is required for high-intensity red indication. The low forward voltage of 1.9V suits low-power applications. Verify that the 130-degree viewing angle meets the line-of-sight requirements of the enclosure design.

LED Indication - Discrete Part Context

This part belongs to the HT-191 series of top-view LEDs manufactured by Harvatek. The series utilizes standard SMD packaging for automated assembly. The HT-191USD-5313 specifically denotes the ultra-bright red variant within this product family.
