LTL-4291N

LED Indication - Discrete Overview

The LTL-4291N is a single-color LED lamp manufactured by Lite-On Inc., featuring an orange diffused lens and a T-1 (3mm) diameter package. It utilizes AlInGaP technology to produce red-orange light with a typical wavelength of 605 nm. The component is designed for radial mounting on printed circuit boards or panels, offering high luminous intensity and wide viewing angles suitable for general-purpose indicator applications.

LED Indication - Discrete Feature Summary

• High luminous intensity output for clear visibility
• Versatile mounting options on PCBs or panels
• IC compatible with low current requirements
• Popular T-1 diameter package design

LED Indication - Discrete Applications

• General-purpose status indicators
• Panel mount instrumentation displays
• Consumer electronics power indicators
• Industrial control system signaling

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the official Lite-On datasheet to confirm lens type and color binning. Ensure the selected variant matches the required forward voltage and current specifications for the target circuit design. Confirm RoHS compliance status if environmental regulations apply to the end product assembly process.

LED Indication - Discrete Selection Notes

Select this component when a standard 3mm through-hole form factor is required for panel or board integration. Consider the orange diffused lens characteristics for visibility needs in ambient lighting conditions. Verify that the operating temperature range meets the environmental constraints of the intended deployment scenario.

LED Indication - Discrete Part Context

This part belongs to the LTL-42xxN series of T-1 LEDs from Lite-On, which are widely used in industrial and consumer electronics. The series is known for its reliability and consistent performance in indicator roles. It represents a standard solution for visible light signaling where compact size and moderate brightness are prioritized over high-power illumination.

LED Indication - Discrete Replacement Considerations

Direct substitutes include LTL-4292N and LTL-4296N from the same manufacturer family. These alternatives share the T-1 package but may differ in lens transparency or specific intensity bins. Always cross-reference electrical parameters before substitution.
