LED Indication - Discrete

Discrete LED indicators are small lighting devices, often used as signal and/or indicator lamps on electronic devices. Signal lamps alert operators to a problem, to identify device status and functions, and to signal the presence of high-voltage or other hazardous conditions. Indicator lamps identify the presence of low-voltage conditions. The 5219458F device is a discrete LED indicator.The 5219458F is an Ultraviolet LED indicator meant for use as both a signal and indicator lamp. It is an extremely small device and has an integrated current limiting resistor to offer protection against LED burnout. The LED indicator is manufactured in an omnidirectional, clear or gray housing.

Application Field

The 5219458F LED indicator is best suited for use in office and industrial equipment, automotive electronics, medical equipment, telecommunications and home electronics such as remote controls, calculators, and gaming systems. Among its features and benefits are its long life and superior UV sensitivity, even at low currents.

Working Principle

The working principle of the 5219458F LED indicator is quite simple. It consists of a single light emitting diode (LED) which is connected to a current limiting resistor and is encapsulated in a clear or gray housing. The resistor works to limit the amount of current that passes through the LED, protecting it from burnout due to excessive current.When power is applied, the current through the LED increases and the light emitted by the LED becomes visible. The brighter the light, the higher the current. The color of the light is dependent on the type of LED used, in this case it is an Ultraviolet LED indicator.

Conclusion

The 5219458F LED indicator is an extremely reliable, long-lasting and small device which is best suited for use in office, industrial and medical equipment, home electronics, and automotive electronics. It is a discrete LED indicator which works on a simple principle of passing current through a light emitting diode. The resistor works to limit the amount of current, protecting the LED from burnout due to excessive current. With its superior UV sensitivity, the 5219458F LED indicator makes a great choice for these applications.
