553-0211-300F is a bi-color diffused LED indicator combining 2 mA red and yellow LED elements designed for status indication and visual feedback applications. The device features red diffused LED in position 1 and yellow diffused LED in position 2, with typical luminous intensity of 2.5 mcd for red and 4.5 mcd for yellow at 2 mA forward current. Operating characteristics include forward voltage of 1.7 V to 2.2 V and a viewing angle of 60 degrees, with dominant wavelengths of 623 nm (red) and 588 nm (yellow). The LED is housed in a through-hole package with lead spacing of 0.100 inches and is RoHS compliant, suitable for wave soldering, dip soldering, or hand soldering with lead-free processes at maximum 260°C for 5 seconds. Common applications include status indicators, alarm displays, and control panel signaling where dual-color indication is required.
