3V 0.2W Green 2835 SMD LED (Pack of 8000) STM32 This is a four bandThis is a High Quality 3V 0. 2W Green Colour SMD LED in a 2835 Package. These LEDs consume low power and generally produce a wide angle of light disbursement which can be narrowed through the use of external lenses. The Forward Voltage is 3. 0 3. 2 volts and the Forward Current is 60mA. SMD LEDs are substantially smaller than lead frame type components, they can be used on smaller boards, with higher packing density, less storage area, and smaller
