The 553-0223F is a 3mm bi-level circuit board indicator (CBI) designed for through-hole PCB mounting. This assembly contains two low-current 2mA LEDs: a green LED in position 1 and a yellow LED in position 2. The green LED has a peak wavelength of 565 nm, while the yellow LED has a peak wavelength of 585 nm, and both offer a typical viewing angle of 60 degrees. This RoHS-compliant component is designed to operate over a temperature range of -55°C to +100°C. It is ideal for applications requiring dual-status indication, such as logic level display or fault flagging, on printed circuit boards.
