MT7318A-UR-A

LED Indication - Discrete Overview

The MT7318A-UR-A is a 5mm ultra-bright red LED emitter manufactured by Marktech Optoelectronics. It features a standard through-hole radial package with a clear lens and a peak wavelength of 660nm, while the dominant wavelength is specified at 643nm. The component operates with a forward current of 20mA and a typical forward voltage of 1.9V. It delivers an optical intensity of 200mcd and has a power rating of 72mW. The device utilizes a dome-shaped lens style and is designed for high-intensity visible light emission applications.

LED Indication - Discrete Feature Summary

• High-intensity red light emission capability
• Excellent on/off contrast performance
• Low drive current operation
• Clear colorless lens design

LED Indication - Discrete Applications

• General indicator lighting
• Instrument panel displays
• Visual status signaling

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and thermal characteristics before integration. Ensure that the 5mm through-hole mounting requirements align with the target PCB layout. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the supplier's official documentation for any recent updates to the mechanical dimensions or spectral data.

LED Indication - Discrete Selection Notes

Select this component when a 5mm form factor is required for high-visibility red indication. The low forward voltage and current specifications support energy-efficient circuit designs. Consider the 35-degree viewing angle for directional visibility needs. Evaluate the clear lens option against colored alternatives based on ambient lighting conditions and desired visual impact.

LED Indication - Discrete Part Context

This part belongs to the MT7318 series of ultra-bright LEDs from Marktech Optoelectronics. The series offers various lens colors and beam angles. The MT7318A-UR-A specifically denotes the red variant with a clear lens. It is distinct from other series like the MT7303 which uses a 3mm package. The product line focuses on standard through-hole components for reliable industrial and consumer electronics.

LED Indication - Discrete Replacement Considerations

Direct substitutes include the MT7318A-UR with different lens colors or the MT7320-UR for tapered beam applications. Verify pin compatibility and luminous intensity ratings when considering alternative models from the same manufacturer or competitors.
