Two-color chip LEDs with reflectors
SML-020 Series
The SML-020 series are two-color, high luminance chip
LEDs with reflectors. Two-color chips are built into a
single package. These LEDs are compact and leadless
to allow a high mounting density.
!
!!
!Features
1) Reflectors are used to achieve a high luminance.
2) Two-color emission, rectangular and leadless
(3×2.5 mm).
3) Can be mounted by automatic mounting.
4) Available on tape
