LED indicators, or Discrete LEDs, are used in countless applications to indicate the status of a device or circuit, or to make certain operations visible to the user. A good example of this is a circuit breaker found in many homes and businesses; a green LED indicates when the breaker is on, and a red one indicates when the breaker is off.

In this article, we will explore the application field and working principle of the C503B-AAN-CY0B0251, a common LED indicator used in industrial and consumer electronics.

Application Field

The C503B-AAN-CY0B0251 is a 3mm lens, available in both through-hole and surface mount packages. It is commonly used in a variety of applications, such as circuit indicator, power supply monitoring and control, and status display in communication equipment, lab instruments, home appliances, automotive electronics, and more.

The indicator has a wide angle of 270 degrees, making it suitable for wide viewing angles and making it easier for users to spot the indicator from far distances. It also has a wide range of brightness levels, from 0.2mcd at 2.2V up to 10mcd at 20V.

Working Principle

The C503B-AAN-CY0B0251 is a LED indicator, which works by allowing a controlled amount of electricity to pass through a semiconductor material. When current combines with electroluminescent material within the LED, it creates a visible light that can be seen from an external source – in this case, the lens.

The indicator is designed to be low-power, making it suitable for applications requiring long battery life. It is also designed to be long-lasting, which makes it a popular choice for applications that require reliable performance and durability. Lastly, the indicator is RoHS compliant, meaning it is free of hazardous materials and is safe for use in a broad range of applications.

Conclusion

The C503B-AAN-CY0B0251 is a versatile LED discrete that is suitable for a wide variety of applications. It has a wide viewing angle and a wide range of brightness levels, making it a great choice for applications that need to be easily seen from afar, as well as those that require reliable performance. Lastly, the indicator is RoHS compliant, making it safe for use in a variety of applications.
