SLI-325YCT31W

SLI-325 Series
LED lamps
Direct mount low current circular
LEDs lamps (φ3.2mm)
SLI-325 Series
The SLI-325 series are small 3.2mm LEDs with a lead pitch of 5mm which can be directly mounted on a printed circuit
board. Three colors and two lens types are available for a total of six types, and they are suitable for use in a wide variety
of applications.

!Features
1) Can be directly mounted on a printed circuit board.
2) Available on tape to allow mounting using a 5mm pitch
machine without lead forming.
3) A low overall height of 5.5mm makes it possible to
design a slim unit.
4) Large flange eliminates wobbling after mounting
(stable before and after soldering).
5) High reliability.
