LTST-C170KGKT
Category
The Lite-On LTST-C170KGKT is a high-reliability 0805 package green-yellow LED designed for industrial and automotive applications requiring wide temperature operation. With 35mcd luminous intensity, 130° viewing angle, and -55°C to +85°C operation, it is suitable for status indicators in harsh environments. Critical parameters include 20mA forward current, 571nm wavelength, and 75mW power consumption. Designers should ensure proper thermal management with copper pours and verify compatibility with 2-3V systems. While offering superior temperature tolerance and brightness over standard LEDs, its cost and color limitations may affect cost-sensitive projects.
