GaAs CAUTION This device contains Gallium Arsenide(GaAs). For safety, please observe the following: (1) Do not put devices in your mouth. Gallium Arsenide is dangerous if ingested. (2) Do not burn, crush, or process chemically. It is dangerous to inhale or ingest the gas, powder, or liquid which results from burning, crushing or chemical processing of the devices. (3) Discard devices separately from industrial and domestic wastes in accordance with the method specified by law. 1 Eudyna Devices Inc. FMM3117VN Datasheet Rev. B2 April, 2004 3.
