Description - 3mm RGB LED diode Common cathode

This small and powerful point of light can dazzle you with a spectrum of bright and natural colors. This is a versatile and eye-catching lighting solution that can be used in a wide range of applications. Want to bring your electronic projects to life? Want to add a touch of magic to your designs? This RGB LED is the perfect choice.

This diode is a special type of LED that incorporates three LED components into one, with each of these components emitting light in one of the primary colors: red, green and blue. Thus, by combining the emission of these three colors in different proportions, we can reproduce a wide range of colors, including intermediate colors and custom shades.

The main feature of an RGB LED diode is its ability to change colorin a controlled manner by PWM signals, having the particularity that the three LEDs share a positive connection point (the long pin), while the negative ones are independent. As a result, by varying the intensities of these three colors, we can create thousands of different colors, which makes it ideal for lighting applications that require versatility and control over color.

This is an easy to use and connect diode, with a standard polarization for a hassle-free installation. And you know, being RGB, it offers an unlimited color palette, allowing you to choose between red, green and blue to mix and match to create the perfect hue for your needs.

With a compact size (3mm diameter package) and high luminous efficiency, this is the perfect solution for applications where space is limited and minimal power consumption is required. Likewise, this diode is designed to last, so its lifetime will surprise you and will guarantee a constant performance.

Thus, we are facing an essential element for, for example:

  • Ambient lighting: Create a relaxing atmosphere in your home with soft colors or give life to your parties with an explosion of vivid and natural colors.

  • Signage and advertising: Highlight your business or event with eye-catching and dynamic signs and advertisements that change color cyclically.

  • Robotics and DIY Projects: Add an element of fun and learning to your electronics and robotics projects.

  • Pinball or Arcade Project Lighting: Add a stylish and distinctive touch to your Pinball machine by having its lighting vary as the game progresses.
  • Model and model lighting: Make your models and models come to life with amazing lighting effects.

Take advantage of the versatility and dazzling brightness of our 3MM RGB LED Diode with common cathode to transform your ideas into reality! Ignite your creativity and add a touch of magic with state-of-the-art RGB lighting - don't wait any longer to bring your projects to life!
