SML-210 Series
LED lamps
Small, chip LEDs
SML-210 Series
The SLM-210 series are small, chip LEDs. The
compact and leadless design of these LEDs allows for
high mounting density.
!Features
1) Four colors: red, orange, yellow and green.
2) Rectangular and leadless (2 x 2.5 mm, 0.8 mm thick)
3) Can be mounted by automatic mounting.
