The document describes the features and characteristics of LB L29S, LT L29S SmartLED® 0603 Hyper-Bright LED Lead (Pb) Free products, including their small size, different wavelengths of light emission, and wide range of applications.
The LB L29S (blue) and LT L29S (true green) are 0603 surface‑mount SmartLED® devices with a colorless diffused resin package. Their compact size (1.7 × 0.8 × 0.65 mm) and high optical efficiency make them suitable for flat backlighting of LCDs, mobile phones, switches, displays, toys, outdoor signage, signal and symbol lighting, and marker lights for steps and escape routes.
Key specifications include a dominant wavelength of 470 nm (blue) or 528 nm (green), horizontal viewing angle of 155° and vertical of 135°, typical forward voltage of 3.05 V, forward current of 15 mA, surge current of 150 mA, power consumption of 60 mW, and operation from –40 °C to +100 °C. Ordering information, brightness groups, wavelength groups and packaging details are also provided. This manual is written in German.
