ROHM SLR

SLR-343 Series
LED lamps
Reflecting small LEDs, directly mountable
(φ3.1mm) (no need for solder modification)
SLR-343 Series
The SLR-343 series are small 3.1mm LEDs which can be directly mounted on a printed circuit board. Four colors and two
lens types are available for a total of eight types, and they are suitable for use in a wide variety of applications.
zExternal dimensions (Units : mm)
zFeatures
1) Four colors : red, orange, yellow and green.
2) Two lens types : Colored diffused and Colored clear.
3) High reliability even in case of direct mount.
4) Blow-holeless solder type.
