Working Principle

The working principle behind the 5520122F LED is simple. The LED consists of two parts, a light-emitting diode (LED) and a resistor. When current passes through the LED, it produces light in the form of photons. This photons are emitted in one direction, thus making the device an efficient light source. In addition, the resistor in the device is designed to limit the amount of current passing through the diode and ensure that the device does not overheat.

Conclusion

The 5520122F LED from Kingbright is a versatile device suitable for a wide range of applications, including warning lights, status indicators and circuit boards. This device offers a long-term maximum forward current rating of 50mA, an impressive luminous intensity of 11 CD, and an operating temperature range of -30°C to +85°C. It is based on the simple principle of allowing current to travel through a light-emitting diode and a resistor, thus producing light in the form of photons.
