MT4118-HR-A

LED Indication - Discrete Overview

The Marktech Optoelectronics MT4118-HR-A is a single-color visible emitter LED with a red lens. It features a dominant wavelength of 629 nm and a peak wavelength of 642 nm. The component operates with a forward current of 30 mA and a forward voltage ranging from 2.1 V to 2.6 V. Luminous intensity varies between 19 mcd and 72.8 mcd. It utilizes a 5 mm round through-hole package with a diffused dome lens.

LED Indication - Discrete Feature Summary

• Provides reliable red indication for electronic applications
• Features a diffused dome lens for broad visibility
• Designed for standard through-hole mounting

LED Indication - Discrete Applications

• Electronic status indication
• Panel indicator lights
• General purpose visual signaling

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version for the MT4118-HR-A to confirm exact luminous intensity binning and forward voltage tolerances, as these parameters can vary within the specified ranges. Ensure compatibility with the target circuit's current limiting requirements given the 30 mA forward current specification. Cross-reference the 5 mm radial lead configuration with the PCB footprint design to guarantee mechanical fit during assembly.

LED Indication - Discrete Selection Notes

Select this component when a standard 5 mm red LED with diffused output is required for general indication tasks. The 629 nm dominant wavelength ensures clear visibility in typical ambient lighting conditions. Consider the 2.1 V to 2.6 V forward voltage range when designing the driving circuit to ensure proper biasing without excessive power dissipation or insufficient brightness.

LED Indication - Discrete Part Context

This part belongs to Marktech Optoelectronics' line of single-color visible emitters. It is distinct from other models like the MT2118-G-A (green) or MTAPD series (photodiodes). The MT4118-HR-A specifically addresses needs for red visual feedback in consumer electronics and industrial control panels where standard through-hole form factors are preferred.

LED Indication - Discrete Replacement Considerations

Direct substitutes may include other 5 mm red diffused LEDs from different manufacturers with similar electrical characteristics, such as comparable forward voltage and current ratings. Verify that any replacement maintains the 629 nm dominant wavelength and 5 mm radial package dimensions to ensure mechanical and optical compatibility.
