2016-08-11 High Power Infrared Emitter (940 nm) Version 1.4 SFH 4244 Features: High Power Infrared LED Short switching time The product qualification test plan is based on the guidelines of AEC-Q101-REV-C, Stress Test Qualification for Automotive Grade Discrete Semiconductors. Applications Infrared Illumination for cameras IR data transmission Sensor technology Notes Depending on the mode of operation, these devices emit highly concentrated non visible infrared light which can be hazardous to the human eye. Products which incorporate these devices have to follow the safety precautions given in IEC 60825-1 and IEC 62471.
