The SLR-342VRTJ7 is a LED indication discrete device. It is typically used for aviation, military and aerospace applications as it has passed stringent testing for ‘temperature cycling’, ‘random vibration’, and ‘temperature shock’. It is also used in communication and industrial controls.

The SLR-342VRTJ7 is a two-electrode, surface-mount device that features a blue or red Indium Gallium Nitride (InGaN) light emitting diode (LED). It is designed with a 12Vdc operating voltage, 5mA maximum forward current and 9.8mW optical output. It is a resistive type of device, using either an integral resistor or an external resistor to regulate current. The total package size is 2.0 x 2.8 x 0.7 mm, making it ideal for space-constrained applications since there is no need for wire leads or bulky heat sinks.

The SLR-342VRTJ7 has a superior level of light output with a typical maximum luminous intensity of 2800mcd (at 20mA operating current). It also offers a large temperature range from -55 to + 125°C, making it well suited for a wide range of operating conditions. Another key feature of the SLR-342VRTJ7 is a long-term stability with a high shock and vibration ratings for aviation, military and aerospace applications.

In terms of working principle, the SLR-342VRTJ7 is a simple device. With its external resistor, it serves as a current limiting device. When the voltage is supplied across the LED, current starts to flow, due to the LED\'s forward voltage. The current is regulated using either the integral resistor or an external resistor, and the LED emits light as the current passes through it. An LED\'s intensity of light is proportional to the current that flows through it, and the SLR-342VRTJ7’s 5mA maximum forward current provides the required level of brightness with a long lifespan.

The SLR-342VRTJ7 also features an enhanced polarity protection circuit. This circuit protects LED from any damage caused by mistakenly connecting voltage poles in the wrong direction. The EPP circuit helps to ensure that the LED will not be damaged when connected in the wrong orientation.

Overall, the SLR-342VRTJ7 is an ideal LED indication discrete device for aviation, military, aerospace and communication applications. It offers a long-term stability, a high light output, a wide temperature range and an enhanced polarity protection circuit, making it suitable for a range of operating conditions.
