Small,chip LEDs (Blue . Green)
SML31 ∗ Series
The SML31＊series are small, chip LEDs. The compact and leadless design of these LED
allows for high mounting density.
!Features
!External dimensions (Units : mm)
1) Two colors, three types (Blue and Green)
2) Rectangular and leadless (1.6x0.8mm, 0.8mm thick)
3) Can be mounted by automatic mounting.
