Component Name

3mm DIP Diffused Blue LED (Pack of 10)

Description

The 3mm DIP Diffused Blue LED is a light-emitting diode component designed to emit a blue color light with a diffused lens. This LED is a discrete semiconductor device that converts electrical energy into visible light. The component comes in a pack of 10, making it an ideal choice for various electronic projects, prototypes, and production runs.

Functionality

The primary function of the 3mm DIP Diffused Blue LED is to emit a blue light when an electric current passes through it. The LED is polarized, meaning it has a positive leg (anode) and a negative leg (cathode). When connected to a power source, the LED will illuminate when the positive leg is connected to the positive terminal of the power source and the negative leg is connected to the negative terminal.

Key Features

  • Diffused Lens: The LED features a diffused lens, which scatters the light emitted, producing a softer, more even illumination.
  • Blue Color: The LED emits a blue color light with a wavelength typically in the range of 450-495 nanometers.
  • 3mm Diameter: The LED has a compact 3mm diameter, making it suitable for use in space-constrained applications.
  • DIP (Dual In-Line Package) Configuration: The LED features a DIP configuration, with two pins spaced 2.54mm apart, allowing for easy installation on a breadboard or PCB.
  • Low Power Consumption: The LED is designed to operate at low power consumption, typically in the range of 1.8-2.5 volts and 10-20 milliamps.
  • Recessed Epoxy Lens: The LED has a recessed epoxy lens, which provides protection against environmental factors and enhances the overall durability of the component.
  • Pack of 10: The component comes in a pack of 10, providing a convenient and cost-effective solution for prototyping, production, and experimentation.

Pin Configuration

  • Component Documentation: 3mm DIP Diffused Blue LED (Pack of 10)
  • Overview
  • The 3mm DIP Diffused Blue LED is a common light-emitting diode (LED) used in various electronic projects, offering a bright blue light emission. This component is available in a pack of 10 and features a through-hole DIP (Dual In-Line Package) design.
  • Pin Configuration
  • The 3mm DIP Diffused Blue LED has two pins, which are:
  • 1. Anode (Positive Leg)
  • Pin 1: The anode pin is the longer lead of the LED and is marked with a slight flat edge on the side of the LED package.
  • Function: The anode pin is the positive terminal of the LED, where the current flows into the device.
  • 2. Cathode (Negative Leg)
  • Pin 2: The cathode pin is the shorter lead of the LED.
  • Function: The cathode pin is the negative terminal of the LED, where the current flows out of the device.
  • Connecting the Pins
  • When connecting the pins, it is essential to observe the correct polarity to prevent damaging the LED. Follow these steps:
  • Step 1: Identify the pins: Identify the anode (positive leg) and cathode (negative leg) pins of the LED. The anode pin is typically longer and has a slight flat edge on the side of the package.
  • Step 2: Connect the anode pin: Connect the anode pin to the positive terminal of the power source (e.g., a microcontroller, a battery, or a voltage regulator output).
  • Step 3: Connect the cathode pin: Connect the cathode pin to the negative terminal of the power source (e.g., a microcontroller, a battery, or a voltage regulator output) or to a resistor in series.
  • Step 4: Add a current-limiting resistor (optional but recommended): To prevent the LED from drawing excessive current and to extend its lifespan, add a current-limiting resistor in series with the LED. The resistor value can be calculated based on the LED's forward voltage drop, desired current, and the power source voltage.
  • Important Notes
  • Always observe the correct polarity when connecting the LED to prevent damage.
  • Use a current-limiting resistor to prevent excessive current and ensure the LED operates within its recommended specifications.
  • Handle the LED by its edges or use an anti-static wrist strap to prevent electrical discharge damage.
  • By following these guidelines, you can safely and efficiently connect the 3mm DIP Diffused Blue LED to your electronic project.

Code Examples
### Example 1: Simple LED Connection with a Microcontroller (Arduino)
In this example, we will connect the LED to digital pin 13 of an Arduino Uno board and toggle it on and off using a simple program.
Hardware Requirements:
Arduino Uno board
 3mm DIP Diffused Blue LED
 1k resistor
 Breadboard and jumper wires

  pinMode(ledPin, OUTPUT);
}
void loop() {
  digitalWrite(ledPin, HIGH); // Turn LED on
  delay(1000); // Wait for 1 second
  digitalWrite(ledPin, LOW); // Turn LED off
  delay(1000); // Wait for 1 second
}
```
Note: Make sure to connect the LED's anode to digital pin 13 and the cathode to GND through a 1k resistor to limit the current.
