3MM LED blue
KSh 4.00
In stock
The 3MM LED Blue is a miniature light-emitting diode that emits blue light when an electric current flows through it. Here’s a breakdown of its key characteristics:
- Size: 3 millimeters (mm) in diameter, making it very small and suitable for compact projects.
- Color: Blue light emission
- Lens Type: Likely a clear or diffused plastic lens for better light dispersion and visibility.
- Typical Voltage: 3.0-3.2 Volts (V) (may vary slightly depending on the manufacturer)
- Typical Current: 20 milliamps (mA)
Additional Considerations:
- Forward Current: It’s important not to exceed the recommended forward current (typically 20mA) to prevent damaging the LED.
- Resistor: A series resistor is generally required when connecting the LED to a power source with a higher voltage. This resistor limits the current flow and protects the LED from burning out. You can use online calculators or datasheets to determine the appropriate resistor value for your specific voltage.
- Brightness: The brightness of the LED can vary depending on the specific model and manufacturer.
- Applications: Due to their small size, low power consumption, and vibrant blue color, these LEDs are widely used in various applications, including:
- Indicator lights (power on/off, status indicators)
- Backlighting for displays or buttons
- Decorative purposes in electronics, appliances, and hobbyist projects
