SFH 4451 ams OSRAM, Mini MIDLED 860nm IR LED, SMD package

The SFH 4451 Mini MIDLED IR emitter, from Osram Opto Semiconductors, produces a narrow beam with a half-angle of 17° and radiant intensity of 60mW/sr at 100mA. The focused beam is achieved through the use of a metalized reflector integrated into the Mini MIDLED. This compact IR LED is only 0.9mm high, making it ideal for applications where high radiant intensity is required but space is limited, such as: light barriers, control and drive circuits, smart phones and optical touch screens.

Highly efficient IR LED
Short switching times
Narrow half angle
Low profile SMT package: 2.3 x 1.95 x 0.9 mm.
Dark coloured surfaces, so the Mini MIDLED can be mounted discretely behind a smart phone cover

Depending on the mode of operation, these devices emit highly concentrated non-visible infrared light which can be hazardous to the human eye.
