Pin Configuration

3 mm Yellow LED (Pack of 10) Component Documentation
Overview
The 3 mm Yellow LED is a standard through-hole LED component used for indicating purposes in various electronic circuits. This documentation explains the pinout and connection details of the LED.
Pinout
The 3 mm Yellow LED has two pins:
Pin 1: Anode (Positive Leg)
Function: The anode is the positive terminal of the LED.
Polarity: The anode is marked with a longer leg or a flat edge on the plastic casing.
Connection: Connect to the positive voltage source or the collector of a transistor (if used as a switch).
Pin 2: Cathode (Negative Leg)
Function: The cathode is the negative terminal of the LED.
Polarity: The cathode is marked with a shorter leg or a round edge on the plastic casing.
Connection: Connect to the negative voltage source or the emitter of a transistor (if used as a switch).
Connection Guide
To connect the 3 mm Yellow LED:
1. Determine the polarity: Identify the anode (positive leg) and cathode (negative leg) by looking for the longer leg or flat edge (anode) and shorter leg or round edge (cathode) on the plastic casing.
2. Connect the anode: Connect the anode (positive leg) to the positive voltage source or the collector of a transistor (if used as a switch).
3. Connect the cathode: Connect the cathode (negative leg) to the negative voltage source or the emitter of a transistor (if used as a switch).
4. Add a current-limiting resistor (optional): If you're connecting the LED directly to a voltage source, add a current-limiting resistor in series with the LED to prevent excessive current and potential damage.
5. Verify the connection: Double-check the polarity and connections to ensure the LED is connected correctly.
Important Notes
Always follow proper safety precautions when working with electronics, including using protective gear and avoiding electrical shock hazards.
The 3 mm Yellow LED may have varying brightness and color intensity depending on the specific batch and manufacturer.
Be sure to check the datasheet or manufacturer's documentation for specific information on the LED's characteristics and recommended operating conditions.
