LL4148

LL4148 is a type of light-emitting diode (LED). It is a small surface-mount device often used in indicator lights, backlighting, and general illumination applications. This particular LED is known for its red color emission. It typically operates at a forward voltage of around 2.0 to 2.2 volts and can handle a forward current of approximately 20 milliamperes. The wavelength of the emitted light is generally in the range of 620 to 630 nanometers.

The LL4148 is characterized by its compact size, making it suitable for integration into various electronic circuits and products where space is a constraint. Its reliability and relatively low power consumption contribute to its widespread use. Manufacturers often specify its luminous intensity, which indicates the brightness of the emitted light. This component is commonly found in consumer electronics, automotive dashboards, and industrial control panels. Its simple two-terminal structure allows for easy integration into printed circuit boards through standard surface-mount technology (SMT) processes. The robust construction of the LL4148 ensures a long operational lifespan.
