The AA3528LSECKT/J3 LED indication device is a versatile LED indicator that is suitable for various applications. This article will look at the application fields and working principles of this LED indicator.

Overview of the AA3528LSECKT/J3 LED Indicator

The AA3528LSECKT/J3 LED indicator is a product from Agilent Technologies. It is an LED-packaged version of the AA3517S and is a lightweight, small form factor, RoHS-compliant discrete indicator for industrial and commercial applications. The device consists of a single red or green source package with a minimum life expectancy of 30,000 hours. The device has a wide operating temperature range of -40°C to +125°C, and it is rated with a peak forward voltage at 1.5-3.5V, a forward current of 10-20mA and a reverse current of 1-2mA.

Application Fields

The AA3528LSECKT/J3 LED indication device is suitable for various fields of application. These include automotive, electrical, communications, medical, industrial process control, indicators, tachometers and LED bar-graphs. In particular, it is ideal for low-power, high-current applications such as backlighting, edge lighting, signs and alarms. Given its wide range of operating temperatures, the AA3528LSECKT/J3 LED indication device is also suitable for applications in harsh environments.

Working Principle

The working principle behind the AA3528LSECKT/J3 LED indication device is simple. An electrical current flows from the voltage source (usually a battery) across a resistor and into the LED. The LED then emits energy in the form of visible light. The level of illumination depends on the amount of current flowing through the LED. Generally speaking, the larger the current, the brighter the LED. The resistor acts as a “current limiter”, preventing the LED from being over-stimulated with too much current and thus being damaged.

Conclusion

The AA3528LSECKT/J3 LED indicator is a versatile, low-cost discrete indicator suitable for a range of applications. Its wide operating temperature range and resistance to harsh environments make it a reliable solution for industrial and commercial applications. The wide range of applications includes automotive, medical, industrial and commercial, and the working principle of the device is relatively simple. All in all, the AA3528LSECKT/J3 LED indicator makes for an ideal solution for the visual indication of system status.
