  • SSF-LXH475IIIXD application field and working principle

    The SSF-LXH475IIIXD is a light emitting diode (LED) indicator, available in red, green, yellow and orange colors. It is commonly used for circuit board indicators, arrays, light bars, and bar graphs. The device operates from a DC voltage source, usually from 3V to 6V. It has a low current consumption of typically 2.5 mA, and can illuminate up to 3 mcd rated luminous intensity. The design of the device includes a white diffused epoxy lens, which ensures evenly dispersed light over a wide viewing angle of up to 140°. The SSF-LXH475IIIXD is available in an 8-pin DIP package with a length of 5.75 mm (0.23”) and a width of 4.3 mm (0.17”).

    The SSF-LXH475IIIXD LED indicator is used in a variety of applications, including displays, warning lights, backlighting, and safety lights. It can be used as an indication of power on/off, error indication, fault indication, low battery warning, and alert notification. The device can also be used in automotive and industrial applications, such as instrumentation, heaters, flow meters, and medical equipment. It is suitable for use in harsh environments with temperatures ranging from -40°C to 85°C. The SSF-LXH475IIIXD is available in a variety of colors and intensities to suit various requirements.

    The SSF-LXH475IIIXD LED indicator works by utilizing a principle known as electroluminescence. When a voltage is applied, current flows through the diode from the anode to the cathode. This forms a junction between the semiconductor materials, and causes the electrons to become excited, releasing energy in the form of photons, which are visible in the form of light. The light produced is proportional to the amount of current flowing through it. The optical properties of the device such as brightness, intensity and wavelength, depend on the material used for the anode and the cathode.

    In summary, the SSF-LXH475IIIXD LED indicator is a reliable and low power device suitable for circuit board indicators, arrays, light bars and bar graphs. It can work in a wide range of temperatures, and is available in various colors and intensities. The device is based on the principle of electroluminescence, which enables it to produce light when energized with a suitable DC voltage source.
