LB M673 and LT M673 are TOPLED® Hyper-Bright LEDs with white SMT package, features small size and high brightness, suitable for applications with small space requirements.
The Hyper Mini TOPLED series from OSRAM provides a compact, lead‑free LED package suitable for applications with limited space. Available in blue (471 nm) and true green (532 nm) wavelengths, the devices feature a Lambertian 120° viewing angle and optical efficiencies of 2 lm/W (blue) and 8 lm/W (green).\n\nThese LEDs are designed for a wide range of uses, including outdoor information displays, backlighting for LCDs, switches and keys, automotive interior lighting, marker lights, and signal/symbol illumination. They are compatible with all standard SMT assembly techniques and can be soldered using IR reflow or TTW processes. The components meet RoHS requirements and are rated for operation from –40 °C to +100 °C. This manual is written in German.
