As we know, those blue LED, green LED and white LED are very sensitive for the static. When some of our customer got a high requirement on this anti-static ability, we will produce this SMD LED or Through-hole LED with our unique technology to make sure the LED work perfect or we will produce this LED with CREE's chips, which can make sure the quality won't changed by the static. However, for IR LED, the static problem won't be a problem on the static. Because of the IR LED chip got great performance for this case, which Anti static index can be more over 10w Volt. This SMD LED's size is 2.8*3.5*0.8mm, The different between 2835 SMD LED and 3528 SMD LED are the thickness (the former just got 0.8mm and the 3528 LED got 1.9mm) and if there have the heat sink on the bottom of the SMD LED. With this case, the other color or wavelength are also available: 2835 SMD IR LED, 2835 Red SMD LED, 2835 Blue SMD LED, 2835 Green SM…
