Infrared light emitting diode, top view type

SIR-568ST3F

The SIR-568ST3F has the response speed and luminous output necessary for image transmission in audio-visual

applications. It can support almost all types of optical transmission through air, including audio and data transmission. The

luminous output is 13mW and the cutoff frequency is 50MHz.

zApplications

Transmission of images from a video cassette recorder

to a television.

Transmission of audio signals between audio devices.

High speed data transmission.

zFeatures
