MARL 3mm Red Through Hole LED Indicator, 20mA, 35mcd

The MARL 3mm Red Through Hole LED Indicator is a single-way, printed circuit board (PCB) mount component designed for versatility and reliability across a broad spectrum of electronic applications. Its primary function is to provide a clear visual signal, making it an essential part of indicator panels, diagnostic equipment, and status displays.

Housed in a robust nylon66 (A82) material, this LED offers significant benefits including UL94V-0 flame retardancy and high impact strength, ensuring durability in demanding environments. The housing material has a melting point of 200–220°C, making it fully compatible with most standard automatic soldering processes without risk of damage during assembly.

Key advantages of this component include its standard luminous intensity and wide viewing angle, courtesy of its diffused lens design, which ensures the emitted red light is visible from various positions. It is engineered for reduced power consumption, drawing a forward current of just 20mA, which contributes to more energy-efficient designs. Its compact T-1 (3mm) through-hole package saves valuable space on the PCB, facilitating higher-density board layouts and semi-custom designs.

By conforming to stringent industrial requirements and the UL94V-0 flammability standard, it guarantees outstanding reliability and safety in operation. The product's design also contributes to saving assembly time, streamlining the manufacturing process for both prototyping and volume production.

Typical Applications:

• LED status and indicator lighting for industrial control panels
• Diagnostic and fault indication in electronic devices
• Power-on and operational status signals in consumer and commercial equipment
• Integration into semi-custom PCB designs requiring a reliable, space-saving visual component
