The 553-0221F is a dual-position LED indicator featuring a green LED in position 1 and a red LED in position 2, designed for visual status signaling in control panels and electronic equipment. Operating at 10 mA per LED, the green LED delivers 5.6 to 12.6 mcd luminous intensity with a dominant wavelength of 564–573 nm and forward voltage of 2.1–2.6 V, while the red LED provides 2.5 to 8.7 mcd with a dominant wavelength of 615–632 nm and forward voltage of 2.0–2.6 V. Both LEDs are rated for continuous forward current of 30 mA maximum, peak forward current of 90 mA (1/5 duty cycle, 1 ms pulse width), and operate across -55 °C to +100 °C with a storage temperature range of -55 °C to +100 °C. The device features a 60-degree viewing angle for both colors and is suitable for indicator panels, alarm systems, and status monitoring in industrial and commercial applications.
