Discrete LED indication is an important part of many industrial, commercial and residential electronic applications. The LTST-321KSKT is a common discrete LED indication device manufactured by Lite-On Technology Corporation. It is a highly reliable, cost effective and versatile device that is suitable for a wide range of applications.

The LTST-321KSKT is a low-current LED indicator device with a peak forward current of 10mA and an operating voltage of 4.5V to 5.5V. It features a 5mm round housing, a wide viewing angle of over 120°, fast response time of 500 µs (max) and a minimum luminous intensity value of 120mcd (typ). The LTST-321KSKT also provides a high accuracy temperature stability of ±0.1°C (typ). It provides two input signals that can be selected for either a discrete or an active level that can be easily adjusted with the potentiometer on the device. The LTST-321KSKT is also RoHS compliant and is available in various colors.

The LTST-321KSKT is commonly used in applications such as environmental monitoring, status indicators, and machine diagnostics. It is ideal for use in densely packed systems and applications where flexibility is essential due to its small size, low power requirements, and long life. It is also commonly used in data transmission systems to detect the status of the transmission.

The LTST-321KSKT’s working principle is fairly straightforward. When the device is powered, the input signal is sent to the device’s comparator circuit. If the sensed signal is above or below the threshold, the device will activate its indicator output or turn its indicator off. The indicator output can be configured to either actively switch or remain in a discrete low input state. Furthermore, the brightness and direction of the indicator can be adjusted as required through a potentiometer on the device. The device is optimized to respond quickly to changes in voltage, keeping the device visible even when the signal is weak.

The LTST-321KSKT is a versatile and useful discrete LED indication device, used in a variety of applications throughout the industrial, commercial and residential sector. Its small size, low power requirements, and extended life make it an ideal choice for a wide range of applications, from environmental monitoring to machine diagnostics and data transmission. The LTST-321KSKT’s working principle is also relatively easy to understand, making it easy to integrate into existing systems as well as developing new applications. With its wide operating temperature range and affordable price, the LTST-321KSKT is a popular option for many users.
