3MM LED red
KSh 4.00
In stock
The 3MM LED Red is a tiny light-emitting diode that emits red light when electricity passes through it. It’s a very common and versatile component used in electronics. Here’s a rundown of its key specifications:
- Size: 3 millimeters (mm) in diameter, making it very small and ideal for tight spaces in projects.
- Color: Red light emission
- Lens Type: Likely a clear or diffused plastic lens to disperse the light for better visibility.
- Typical Voltage: 1.8-2.2 Volts (V) (may vary slightly depending on the manufacturer)
- Typical Current: 20 milliamps (mA)
Additional Points to Consider:
- Forward Current: It’s crucial 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 readily available red color, these LEDs are incredibly versatile. They are widely used in electronics, appliances, and hobbyist projects for:
- Indicator lights (power on/off, status indicators)
- Backlighting for displays or buttons
- Decorative purposes
- Simple signaling applications
