SML-010 Series LED lamps Chip LEDs with reflectors SML-010 Series The SML-010 series are high luminance chip LEDs with reflectors. The compact and leadless design of these LEDs allows for high mounting density. Features External dimensions (Units : mm) 1) Reflectors are used to achieve a high luminance. 2) Four colors : red, orange, yellow and green. 3) Rectangular and leadless (3x2mm) +0.2 1.3 3.0 0.1 4) Can be mounted by automatic mounting. 2.3 0.3 0.5 Through hole Cathode mark 2R0.3 Electrode 1.6 Tolerances are 0.2 unless otherwise noted: Selection guide Emitting color Red Orange Yellow Green Lens SML-010LT SML-010DT SML-010YT SML-010MT Transparent clear SML-010VT SML-010FT SML-010PT Absolute maximum ratings (Ta=25C) Limits Parameter Symbol Unit Bright red (L) Other colors Power dissipation PD 75 70 mW Forward current IF 30 25 mA mA Peak forward current IFP 75 60 VR V Reverse voltage 4 Operating temperature Topr 30~+85 C Storage temperature Tstg 40~+85 C Pulse width 1ms Duty 1 / 5 2.0 1.7 1.6SML-010 Series LED lamps Electrical and optical characteristics (Ta=25C) Parameter Reverse Peak Spectral line Forward voltage Luminous intensity current wavelength half width Color VF (V) Cond.
