5mm blue LEDs with diffused lens and good brightness.

DESCRIPTION

These are general purpose 5mm blue LEDs with diffused lens and good brightness.

PACKAGE INCLUDES:

LED Polarity

  • Qty 10 – Blue diffused 5mm LEDs

KEY FEATURES OF LED BLUE 5MM DIFFUSED:

  • General purpose LEDs
  • Blue color (470nm wavelength)
  • 5mm diameter
  • Diffused lens for wide viewing angle
  • 20mA max drive current
  • Forward voltage drop 3.2V

These are general purpose 5mm LEDs with diffused lens and good brightness that work well for general indicator use.

The shorter of the two leads and flat side of the housing denotes the cathode.

For size comparison, a 3mm, 5mm and 10mm LED are shown to the right.

LED Size Comparison

 

The LEDs are logic compatible with a max drive current of 20mA and a forward voltage drop of approximately 3.2V.

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 91 ohms will provide max brightness.  A larger resistor of around 150- 470 ohm can be used to reduce current at a lower brightness.
