LED lamps Reflecting small LEDs, directly mountable (?3.2 mm) SLR-325 Series The SLR-325 series are small 3.2 mm LEDs with a lead FExternal dimensions (Units: mm) pitch of 5 mm which can be directly mounted on a printed circuit board. Two colors and four lens types are available for a total of eight types, and they are suitable for use in a wide variety of applications. FFeatures 1) Can be directly mounted on a printed circuit board. 2) Available on tape to allow mounting using a 5 mm pitch machine without lead forming. 3) A low overall height of 5.5 mm makes it possible to design a slim unit. 4) Large flange eliminates wobbling after mounting (stable before and after soldering). 5) LED arrays at a conventional 4 mm pitch are also possible. 6) High reliability.
