LTST-C190GKT
Category
The Lite-On LTST-C190GKT is a 20mA, 569nm green-yellow LED with 130° viewing angle and 100mW power, designed for industrial applications requiring wide temperature operation (-55°C to +85°C). Its 0603 package offers compact integration while maintaining 6mcd luminous intensity. Key considerations include proper soldering techniques, current/voltage limits, and thermal management through 10mil copper traces. Alternative models match core parameters within ±5% tolerance but differ in wavelength range and voltage specifications. Best suited for cost-sensitive projects needing reliable status indication in harsh environments.
