ams OSRAM SFH 7018

The new MULTILED^® SFH 7018A & SFH 7018B feature a highly reflective QFN package for significantly increased light output. Their sophisticated 2-cavity design reduces interferences between green chip on the one hand and red and IR chip on the other hand. Furthermore, the 2 cavities enables the light sources to be optimally placed relative to their respective photodiodes. Overall this leads to higher accuracy of measurement of vital signs (e.g. heart rate, SpO2).

SFH 7018A is optimized for low V_f at high current allowing operation without voltage booster in many cases.

SFH 7018B is optimized for maximum brightness.
