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.
