OSRAM LR W5KM / LY W5KM LED Datasheet
The LR W5KM (red) and LY W5KM (yellow) are white SMD thin‑film LEDs designed for display backlighting, automotive interior/exterior lighting, portable lighting and decorative applications. They feature a colorless clear silicone resin package and high luminous efficiency in a compact form.
Key specifications include peak wavelengths of 632 nm (red) and 597 nm (yellow), a 160° viewing angle, typical optical efficiency of 72 lm/W (red) and 74 lm/W (yellow) at 100 mA, forward voltage around 2.0 V, maximum forward current of 400 mA, and a power consumption of 1.1 W. The devices are supplied on 24‑mm tape with 200 units per reel (Ø180 mm) and require moisture‑sensitive handling per JEDEC standards. This manual is written in German.
