These are general purpose large 10mm red LEDs with diffused lens and good brightness.
- Qty 5 – Red diffused 10mm LEDs, General Purpose
KEY FEATURES OF LED RED 10MM DIFFUSED:
- General purpose LEDs
- Red color (625nm wavelength nominal)
- Large 10mm diameter
- Diffused lens for wide viewing angle
- 20mA max drive current
- Forward voltage drop 2V
These are general purpose 10mm LEDs with diffused lens and good brightness that work well for general indicator use. The large size is handy when a larger indicator is desired.
The shorter of the two leads denotes the cathode. Note that there is usually a flat surface on both sides of the housing, so you cannot rely on that as the cathode indication.
For size comparison, a 3mm, 5mm and 10mm LED are shown to the right.
The LEDs are logic compatible with a max drive current of 20mA and a forward voltage drop of approximately 2V.
A current limiting series resistor is needed to protect the LED and/or the device being used to drive it.
At an operating voltage of 5V a series voltage dropping resistor of 150 ohms will provide max brightness. A larger resistor of around 220- 470 ohm can be used to reduce current at a lower brightness.
