LED Assortment Diffused 5mm General Purpose (20-Pack)

5 each of red, green, yellow and blue LEDs.

DESCRIPTION

This is a general purpose LED assortment that contains 5 each of red, green, yellow and blue 5mm diffused LEDs.

PACKAGE INCLUDES:

• Qty 5 – Red diffused 5mm LEDs
• Qty 5 – Green diffused 5mm LEDs
• Qty 5 – Yellow diffused 5mm LEDs
• Qty 5 – Blue diffused 5mm LEDs

KEY FEATURES OF LED ASSORTMENT:

• General purpose LEDs
• 5mm diameter
• Diffused lens for wide viewing angle
• 20mA max drive current
• Forward voltage drop of 2V for red, green and yellow colors.  3.2V for blue

These are general purpose 5mm LEDs with diffused lens and good brightness that work well for general indicator use.  They come in a 20-pack and are perfect for stocking the project parts bin.

They are logic compatible with a max drive current of 20mA and a forward voltage drop of approximately 2V for the red, green and yellow LEDs and 3.2V for the blue LED.

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 for red/green/yellow LEDs or 91 ohm for the blue LEDs will provide max brightness.  A larger resistor of around 220- 470 ohm can be used to reduce current at a lower brightness.
