LTST-C190KRKT
Category
The Lite-On LTST-C190KRKT is a 0603-sized red LED offering robust performance for general indication applications. With a 20mA forward current, 631nm wavelength, and 130° viewing angle, it provides reliable status signaling in consumer and industrial devices. Its operating temperature range (-30°C to +85°C) and 62.5mW power consumption make it suitable for diverse environments. Designers should ensure proper thermal management and soldering techniques to maximize lifespan. While cost-effective at volume, its limited wavelength options and high minimum order quantities may pose constraints for some applications.
