This is the Red variant of the Red 3mm LED Diffused (Pack of 50) in Through Hole DIP LEDs. Available at ₹42.60 (₹36.10 + GST) with free shipping across India.
Product Description
- A Red 3mm LED Diffused is a type of semiconductor light source with two leads. It emits light when powered. When a suitable voltage is applied across its terminals, electrons within the device recombine with electron holes, emitting energy as photons. This phenomenon is called electroluminescence, and the LED’s color is determined by the energy bandgap of its semiconductor material.
- The Red 3mm LED Diffused is a small light-emitting diode with a diameter of 3mm. It emits a red-colored light when activated. The “diffused” designation indicates that the emitted light is spread out rather than being concentrated in a narrow beam. This type of LED is commonly used in various electronic devices for indicator lights, displays, and decorative lighting applications.
Features:
- High Brightness
- Low Current Consumption
- Large Operating Voltage Range
- Wide Operating Conditions
Package Includes:
- 50 x Red 3mm LED Diffused (Pack of 50)

How to Use Red 3mm LED Diffused
Insert the LED’s leads into your PCB or breadboard, observing polarity (long lead = anode, short lead = cathode). Solder or secure the leads, then connect a suitable current-limiting resistor in series (commonly 220 Ω at 5 V) to the anode and ground the cathode. Apply power to see a steady red illumination.

Frequently Asked Questions
Can I use the Red 3mm LED Diffused on a breadboard?
Yes. The standard through-hole leads fit most solderless breadboards. Simply insert the leads, add a current-limiting resistor, and power your circuit.
What resistor should I pair with these 3 mm LEDs?
For a 5 V supply, a 220 Ω resistor in series will limit current to around 20 mA. Increase the resistor value if using higher voltages to protect the LED.
How do I identify the LED polarity before soldering?
The longer lead is the anode (+) and the shorter lead is the cathode (−). You may also notice a flat edge on the LED housing marking the cathode side.
