ams OSRAM MULTILED® SFH 7018x for Vital Sign Monitoring feature a highly reflective QFN package for significantly increased light output. These three-in-one, high-performance multi-emitters for green, red, and infrared target heart rate and SpO2 monitoring. A sophisticated two-cavity design reduces interferences between the green chip and the red/IR chip. The two cavities enable the light sources to be optimally placed relative to the respective photodiodes, providing higher measurement accuracy of vital signs. The SFH 7018A is optimized for maximum brightness and low Vf at a high current, allowing operation without a voltage booster in many cases.
