LS 3386-Q1R2-1

LED indicators are widely used in automotive, medical and industrial applications. They offer many advantages over traditional indicators, such as low power consumption and improved visibility. The LS 3386-Q1R2-1 is a discrete, colored LED indicator for industrial use. This article provides an overview of the LS 3386-Q1R2-1 LED indicator\'s application field and working principle, allowing engineers to understand the capabilities of this LED indicator in greater detail.

Application Field

The LS 3386-Q1R2-1 is a single package LED indicator, available in green, yellow and red varieties. As a discrete LED indicator, it is suitable for applications requiring a single color warning or indicator light, such as on an industrial control panel or in a medical device. The LS 3386-Q1R2-1 also meets RoHS requirements, making it an ideal choice for any application which requires compliance with environmental regulations.

The LS 3386-Q1R2-1 LED indicator features a narrow 2-pin configuration and a low profile of only 3.45mm, making it ideal for applications which have limited space. The LED has excellent brightness and reliability, with an operating temperature range of –40 ºC to +105 °C for even the most extreme operating environments.

Working Principle

The LS 3386-Q1R2-1 LED indicator is powered by a low current DC voltage. To switch on the indicator, the applied voltage between the anode and cathode of the indicator must exceed the forward voltage of the indicator, which is typically between 1.7 and 2.4V. This voltage then causes the indicator to emit light. The intensity of the light emitted is proportional to the current rate flowing through the LED, which can be described by the equation: I = V/R, where V is the applied voltage and R is the resistance of the LED.

The LS 3386-Q1R2-1 also features a built-in thermal protection circuit which is designed to protect the LED indicator from overheating. When the temperature reaches a certain set point, the current to the LED is automatically reduced or switched off until the temperature returns to an acceptable level. This helps to ensure the longevity of the indicator and improve its overall reliability.

Conclusion

The LS 3386-Q1R2-1 is an ideal choice for applications which require a discrete, colored LED indicator. It offers a narrow two pin configuration, good brightness and excellent reliability in a low profile package. The low power consumption and thermal protection circuit further add to the versatility of this LED indicator. By understanding their application field and working principle, engineers can be confident in selecting the LS 3386-Q1R2-1 LED indicator for their needs.
