| SML-810MT Light Emitting Diodes Reverse mount type chip LED SML- 810MT The SML-810 is reverse mount type chip LEDs. Due to reverse mounting , it will make thinner for the sets. !Features 1) Green colored light emisson. 2) Small shaped (3.4x1.25mm). 3) Can be mounted by automatic mounting. !External dimensions (Units : mm) 3.4 +0.2 0 1.2 R 1.25 4-R 0.3 Resisit 1.25 Cathode Index 0.28 Electrode 1.8 (units : mm) Tolerances are 0.1 unless otherwise noted: !Selection guide Emitting color Green Lens Clear SML-810MT !Absolute maximum ratings (Ta=25C) Parameter Power dissipation Forward current Peak forward current Reverse voltage Operating temperature Storage temperature Symbol PD IF IFP VR Topr Tstg Limits 65 25 60 4 -30~+85 -40~+85 Unit mW mA mA V C C Pulse width 1ms Duty 1/5 1.1 1/3 SML-810MT Light Emitting Diodes !Electrical and optical characteristics (Ta=25C) Parameter Color Type SML-810 MT Green Forward voltage VF (V) Typ. 2.2 Reverse current Luminous intensity IV (mcd) Min. 5.6 Peak wavelength Spectral line half width Cond.
