Additional Details

The LTR-C1903 series LEDs are designed to operate at low currents, typically around 20mA, making them highly energy-efficient. Their robust construction ensures reliable performance even in harsh environments. The wide viewing angle allows the light to be seen from various positions, improving the visibility of the indication. These LEDs are also compatible with standard through-hole mounting techniques, simplifying the assembly process. The LTR-C1903 LEDs are available in different package styles to suit various application requirements.

These LEDs can be driven directly from logic circuits with appropriate current-limiting resistors. The forward voltage drop varies depending on the color of the LED. The luminous intensity is typically measured in millicandelas (mcd) and is an important factor to consider when selecting the appropriate LED for a particular application. Proper heat sinking may be required for high-current applications to ensure long-term reliability.
