TLHR4900

LED Indication - Discrete Overview

The TLHR4900 is a high-efficiency red light-emitting diode manufactured by Vishay Semiconductor Opto Division. It utilizes a T-1 (3mm) radial package with a clear lens design to maximize optical output. The device operates at a forward voltage of approximately 2V and emits light at a peak wavelength of 619nm. Rated for a test current of 10mA, it provides a millicandela rating of 25mcd. This component is designed through-hole mounting and complies with RoHS3 standards.

LED Indication - Discrete Feature Summary

• High efficiency red LED emission in a standard T-1 form factor
• Clear lens configuration for enhanced light transmission
• Suitable for general indication applications requiring visible red signaling

LED Indication - Discrete Applications

• Panel status indicators
• Power supply visual feedback
• General purpose electronic equipment signaling

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version from Vishay or authorized distributors to confirm exact binning classifications and spectral consistency. Ensure that the procurement documentation explicitly states compliance with RoHS3 regulations as required for modern manufacturing environments. Cross-reference the part number against the manufacturer's official obsolescence notices to confirm availability for new designs.

LED Indication - Discrete Selection Notes

Select this component when a standard 3mm through-hole red indicator is required for circuit visualization. Consider the 2V forward voltage drop when designing series resistor networks to ensure proper current limiting at the 10mA test condition. Evaluate the 25mcd brightness level against ambient lighting conditions to guarantee adequate visibility for the intended application interface.
