(76mm) in diameter on a surface 10 feet (3.05m) away. designed primarily for the encoder industry, the CLE333 has wide application anywhere a very narrow beam pattern is required. note: 5. e e is a measure of irradiance (power/unit area) with in a 0.444" (1.128cm) diamet er area, centered on the mechanical axis of the device and spaced 2.54" (6. 45cm) from the lens side of the tab. this is geometrically equivalent to a 10 cone. clairex ? technologies, inc. ma y , 2005 clairex reserves the right to make changes at any time to improve design and to provide the best possible product. ? absolute maximum ratings (t a = 25c unless otherwise stated) storage temperature ...................................................................... -65 c to +150c operating temperatur e ................................................................... -65 c to +125c lead soldering temperature (1) .......................................................................... 260c continuous forward current (2) ........................................................................ 100ma peak forward current (1.0ms pu lse width, 10% duty cycl e).................................. 1a reverse vo ltage .................................................................................................... 5v continuous power dissipation (3) .................................................................... 200mw notes: 1. 0.06?
