10mm LED Blue

10mm LED Blue

These are general purpose large 10mm Blue LEDs with diffused lens and good brightness.

PACKAGE INCLUDES:

• Qty 1 – Blue diffused 10mm LEDs, General Purpose

KEY FEATURES OF LED RED 10MM DIFFUSED:

• General purpose LEDs
• Blue 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 LED Blue 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.
