Description
LED 3mm Diffused Blue – Through-Hole Indicator LED
The LED 3mm Diffused Blue is a compact, energy-efficient through-hole LED designed for signal indication, DIY projects, and electronic prototypes. Its diffused lens provides a soft, wide-angle glow, making it ideal for control panels, hobby circuits, and applications requiring uniform blue light. With low power usage and long operational life, this LED is suitable for both beginners and advanced embedded system designs.

How to Use
- Connect the long leg (anode) to the positive voltage through a resistor.
- Connect the shorter leg (cathode) to ground.
- A current-limiting resistor of 330E–1K is recommended based on supply voltage.
- Use PWM through microcontrollers for brightness control.
- Ensure forward current does not exceed 20mA.
