EALP05RDHRA2

LED indicators are the most commonly used discrete components for the indication of the status of usually-active signals. This article discusses the EALP05RDHRA2 LED indicator with respect to its application field and working principles.

The EALP05RDHRA2 is a 5 mm self-contained LED indicator designed for PCB mounting. With a tungsten (TW) LED chip and an 8 mcd LED intensity rating, this LED indicator provides excellent brightness and color consistency over a wide range of operating conditions. Its low profile vertical mount housing design allows it to be used in tight spaces while its wide operational temperature range (from -40°C to +70°C) makes it suitable for a variety of applications.

The EALP05RDHRA2 can be used for a variety of different applications, including but not limited to signal indication, industrial control, and warning light applications. It can also be used as a signal repeater device, signalling when a predetermined action has been carried out. The EALP05RDHRA2 has a wide operating voltage range (from DC 2.8V to 20V) and low current rating, making it a suitable choice for high power and/or low voltage applications.

The EALP05RDHRA2 works by converting electrical energy into light energy (luminescence) in the form of visible light waves. The LED emits light in a cone-shaped pattern, depending on the size and shape of the LED chip used. The LED produces a constant and predictable light output, regardless of the applied voltage or power. LED indicators can be controlled using a variety of methods, including pulse width modulation (PWM), current control, and voltage control.

To ensure optimal performance, the LED requires a constant current. Overvoltage protection should be used to prevent the LED from being exposed to overvoltages, as this could cause damage to the LED. A current-limiting device is also necessary to ensure the LED does not draw more current than it is designed to handle.

In conclusion, the EALP05RDHRA2 LED indicator is suitable for a variety of applications and can be used for signal indication, industrial control, and warning light applications. Its wide operating voltage range and low current rating make it suitable for high power and/or low voltage applications. With an 8 mcd LED intensity rating and low profile housing design, the EALP05RDHRA2 provides excellent brightness and color consistency over a wide range of operating conditions.
