SML-712 Series
Light Emitting Diodes
Ultra high brightness side view chip LED
SML-712 Series
The SML-712 series are ultra high brightness side view chip LEDs equipped with an AlGaInP chip. Due to its reflector
constructed inside, it will make higher brightness and suitable for LCD backlights.
!Features
!External dimensions (Units : mm)
1) Because of its structure inside, better reflection will
be made for high brightness.
2.0
2) Better self alignment due to its construction of
electrode on the bottom.
3) 2×1.25, t=0.8mm Super small type
