• Power-on indicators in electronic devices
• Fault or error signaling in industrial equipment
• User feedback in consumer electronics
• Automotive dashboard indicators

Below are the key technical details of the FLE-113-01-G-DV-K:

The FLE-113-01-G-DV-K has two pins for electrical connection. The table below describes the pin configuration:

1. Determine the Operating Voltage: Ensure the power supply voltage matches the LED's operating voltage (2.0V to 3.3V). Use a current-limiting resistor to prevent overcurrent.

2. Calculate the Resistor Value: Use Ohm's Law to calculate the resistor value: [ R = \frac{V_{supply} - V_{forward}}{I_{forward}} ] For example, if the supply voltage is 5V and the forward voltage is 2.2V with a forward current of 20mA: [ R = \frac{5V - 2.2V}{0.02A} = 140\ \Omega ] Use the nearest standard resistor value (e.g., 150Ω).

3. Connect the LED:

   • Connect the anode (longer pin) to the positive terminal of the power supply through the resistor.
   • Connect the cathode (shorter pin) to the ground.

4. Test the Circuit: Power on the circuit and verify that the LED lights up.

• Polarity: Ensure correct polarity when connecting the LED. Reversing the polarity may damage the component.
• Current Limiting: Always use a resistor to limit the current through the LED.
• Heat Management: Operate the LED within the specified temperature range to avoid overheating.
• Panel Mounting: Secure the LED properly in the panel to prevent mechanical stress.

The FLE-113-01-G-DV-K can be easily connected to an Arduino UNO for status indication. Below is an example code to blink the LED:

// Define the pin connected to the LED
const int ledPin = 13; // Use digital pin 13 for the LED

void setup() {
  pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}

void loop() {
  digitalWrite(ledPin, HIGH); // Turn the LED on
  delay(1000); // Wait for 1 second
  digitalWrite(ledPin, LOW); // Turn the LED off
  delay(1000); // Wait for 1 second
}

1. LED Does Not Light Up:

   • Cause: Incorrect polarity.

   • Solution: Verify the anode and cathode connections.

   • Cause: No current-limiting resistor.

   • Solution: Add a resistor in series with the LED.

2. LED Flickers:

   • Cause: Unstable power supply.
   • Solution: Use a regulated power supply or add a capacitor for filtering.

3. LED Burns Out:

   • Cause: Excessive current.
   • Solution: Recalculate the resistor value and ensure it limits the current to 20mA.

4. LED is Dim:

   • Cause: Insufficient voltage or high resistor value.
   • Solution: Verify the supply voltage and adjust the resistor value.

Q1: Can I use the FLE-113-01-G-DV-K with a 12V power supply?
A1: Yes, but you must use an appropriate resistor to limit the current. For a 12V supply, calculate the resistor value as follows: [ R = \frac{12V - 2.2V}{0.02A} = 490\ \Omega ] Use a 470Ω or 510Ω resistor.

Q2: Is the LED waterproof?
A2: No, the FLE-113-01-G-DV-K is not waterproof. Use it in dry environments or enclosures.

Q3: Can I use PWM to dim the LED?
A3: Yes, the LED can be dimmed using Pulse Width Modulation (PWM) from a microcontroller like Arduino.

Q4: What is the lifespan of the LED?
A4: The typical lifespan is 50,000 hours under normal operating conditions.

This concludes the documentation for the FLE-113-01-G-DV-K.
