The 555-4303F is a green LED indicator designed for 5V applications with integrated internal resistor and quad configuration. It features a luminous intensity of 1.0 to 3.0 mcd (typical 3.0 mcd) at 5V forward voltage, with a peak wavelength of 565 nm characteristic of green LEDs. The device has a forward voltage range of 3.5 to 6.7V and a viewing angle of 90 degrees, providing excellent visibility from multiple angles. The LED is housed in a die-cast zinc package with 2mm form factor and is RoHS compliant, suitable for panel-mounted indicator applications in industrial control systems, instrumentation, and consumer electronics requiring reliable visual feedback.
