Blue indicator LED in the 0805 footprint (2.0 × 1.25mm). Blue is increasingly specified for industrial panel indicators as a fourth distinct state color alongside red, yellow, and green — providing unambiguous status differentiation without relying on color conventions that may be ambiguous to color-deficient operators. Luminous intensity 120–210mcd at 20mA nominal drive.
Blue emission at approximately 460–475nm. Forward voltage 1.8–2.6V. Operating temperature −40°C to +85°C.
Detailed electrical and optical characteristics
Blue LEDs exhibit stronger bin-to-bin variation than red or yellow, because InGaN die output is more sensitive to junction temperature and drive current than AlGaInP. Multi-source procurement of blue 0805s frequently results in perceptible hue differences between board assemblies from different production runs. iBright sources S0805BL-CMH1 from a single CMH production line, providing the lot traceability needed to match blue indicators across panel assemblies manufactured months apart.
Blue emission, 460–475nm typical. Catalog lists 620–630nm — confirm wavelength from CMH datasheet.
Applications where this product is commonly specified
High-reliability status indicators and alarm arrays on factory floor equipment.
High-density status indicators for network switches, routers, and server blades.
