TLHF4900

LED Indication - Discrete Overview

The TLHF4900 is a standard through-hole LED manufactured by Vishay Semiconductor Opto Division, featuring an orange illumination color with a wavelength of 605 nm. It utilizes AlInGaP technology within a T-1 (3 mm) clear package to deliver high luminous intensity of 300 mcd at a forward current of 10 mA. The component exhibits a narrow viewing angle of 16 degrees and a forward voltage of 1.9 V. Designed for robust operation, it supports a power rating of 80 mW and functions reliably across a temperature range from -40 C to +100 C.

LED Indication - Discrete Feature Summary

• AlInGaP technology enables very high luminous intensity output in a compact form factor.
• Small mechanical tolerances ensure precise fitment within standard T-1 packages.
• Suitable for both DC operation and high peak current applications.

LED Indication - Discrete Applications

• Indicator lights requiring high visibility
• Panel status displays
• Instrumentation front panels

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the official Vishay datasheet to confirm exact binning for luminous intensity and color coordinates. Ensure the selected variant matches the required forward voltage and viewing angle specifications for the target circuit design. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

LED Indication - Discrete Selection Notes

Select this component when a narrow beam angle and high intensity are critical for visibility over distance. The T-1 package size allows for easy integration into existing through-hole layouts. Consider the 16-degree viewing angle carefully to ensure the light source aligns correctly with the user's line of sight.

LED Indication - Discrete Part Context

This part belongs to Vishay's Standard LEDs - Through Hole category, specifically designed for general indication purposes. The T-1 package is a widely recognized industry standard for 3 mm diameter LEDs, facilitating compatibility with various PCB footprints and mechanical assemblies.

LED Indication - Discrete Replacement Considerations

Consult the official Vishay replacement guide for direct substitutes. Verify that any alternative maintains the same T-1 package dimensions, forward voltage characteristics, and optical intensity requirements to ensure functional equivalence.
