The 553-0133F is a RoHS-compliant, bi-level circuit board indicator equipped with two 3mm yellow LEDs. Each LED operates with a typical forward voltage of 2.1V and a maximum of 2.6V when driven at 10 mA. Under these conditions, it produces a typical luminous intensity of 14.5 mcd and a dominant wavelength of 590 nm, with a 60-degree viewing angle. This component is designed for through-hole mounting and is ideal for status indication, logic level display, and panel indicators in various electronic applications.
