LTST-S320YKT is one of the most commonly used models of LED Indication - Discrete. It is a high intensity, long life two-color surface mount indicator, which is commonly used for on/off indication, momentary indication and on/off indication.The LTST-S320YKT is a combination of two discrete indication devices, an LED and a transistor. An LED emits light when it is activated by a small current and is used to indicate the current state of a circuit. The transistor is used to control the current flowing thru the LED in order to turn it on or off.The LTST-S320YKT has a certain voltage rating and a current rating. The voltage rating is the maximum voltage at which the LED can be safely operated. The current rating is the maximum current the LED can carry without being damaged. The LTST-S320YKT is usually operated at a low voltage, ranging from 2.4V to 5.0V.The main advantages of using the LTST-S320YKT’s two-color combination are its enhanced signal clarity, flexibility and longevity. By using two different colored LEDs, it is possible to indicate in a clearer way the status of the circuit, making it easier to interpret the signal. In addition, the two-color combination of LEDs allows for a higher current carrying capacity, increasing the life time of the product.The working principle of the LTST-S320YKT is simple. In order to turn on the LED in one color, the user has to apply a certain voltage between the anode and cathode of the LED. Typically, this is provided by a separate circuit (external power supply), but it can also be provided by the power of the circuit in which the LED is used. Once the correct voltage is applied, the LED will glow in its designated color.In order to change the LED’s color, the voltage between the anode and cathode must be changed. This is done by using a transistor, which is connected to the LED between the anode and cathode. The transistor is controlled by the user, and the voltage between the anode and the transistor can be adjusted to change the LED’s color. When the voltage is at the correct level, the LED will glow in its designated color.The LTST-S320YKT is a versatile solution for on/off indication and momentary indication. It is commonly used in automotive applications, medical equipment, lighting and signals, security and surveillance systems and other applications where a specific indication is needed. With its two-color combination, the LTST-S320YKT provides a clear, long lasting and cost-effective solution.
