RGB LED – 5mm – Common Cathode

Description

• Size: The LED has a 5mm diameter, which is a common size for through-hole LEDs. This size makes it easy to mount on a printed circuit board (PCB).
• Common Cathode: The “common cathode” configuration means that all three color elements (red, green, and blue) share a common cathode terminal, while each color has its anode terminal. This configuration allows you to control the brightness of each color separately.
• Colors: This RGB LED can emit light in three primary colors: red, green, and blue. By controlling the intensity of each color, you can create a wide range of colors by mixing these primary colors.
• Voltage: To operate this RGB LED, you typically need to provide a low forward voltage to each color element (red, green, and blue) separately. The common cathode is connected to the ground (0V).
• Applications: RGB LEDs are commonly used in various applications where colored lighting is required, such as in displays, indicators, signage, mood lighting, and decorative lighting. They are also popular in DIY electronics and projects involving color-changing effects.
• Control: To achieve different colors, you’ll need to control the brightness of the red, green, and blue elements by using pulse-width modulation (PWM) signals from a microcontroller or other control circuitry. By varying the duty cycle of each color, you can create a wide spectrum of colors.
• Current Limiting: It’s important to use current-limiting resistors when connecting this RGB LED to prevent excessive current flow and potential damage. The appropriate resistor values depend on the forward voltage and forward current ratings of the LED and your power supply voltage.
