Ultra high brightness chip LEDs
SML-512 Series
The SML-512 series are ultra high brightness chip LEDs equipped with an AlGaInP chip. The compact and leadless
design of these LEDs allows for high mounting density.
!Features
1) Three colors : red, orange and yellow.
2) Rectangular and leadless (1.6x0.8mm, 0.55mm thick)
3) Can be mounted by automatic mounting.
