LED 5mm 2Pin

5mm Round LED – Standard 2-Pin Light Emitting Diode (Through-Hole)

Description: The classic 5mm round LED is an absolute essential for every maker, student, and electronics enthusiast. Whether you are learning how to solder, prototyping a new circuit on a breadboard, or adding visual feedback to a custom PCB, this standard 2-pin LED delivers reliable and bright performance. Designed with a traditional dome-shaped lens for excellent light dispersion, it operates at a very low current, making it highly efficient for battery-powered builds. It is the perfect, cost-effective component for bringing your electronic projects to life.

Key Specifications:

1. LED Size: 5mm
2. Lens Shape: Round (Dome Top)
3. Pin Count: 2 Pins
4. Typical Forward Voltage: ~2.0V to 3.2V (Varies depending on the specific color)
5. Recommended Current: 20mA
6. Mounting Style: Through-Hole (Radial Leads)
7. Polarity: Polarized (Longer lead is the Anode/Positive, and the flat edge on the base indicates the Cathode/Negative)

Features:

1. Breadboard & Maker Friendly: The sturdy leads are perfectly sized to slot effortlessly into standard 2.54mm pitch breadboards, perfboards, and female jumper wires.
2. Low Power Consumption: Highly energy-efficient, allowing you to run multiple LEDs directly from microcontroller logic pins without external power drivers.
3. Mistake-Free Installation: Features a clear visual polarity guide (a flat spot on the rim and a longer positive leg) to ensure you always wire it correctly the first time.
4. Universal Standard: The ubiquitous 5mm size means it fits perfectly into standard LED bezels, panel mount holders, and custom 3D-printed enclosures.

Common Applications:

1. The classic "Blink" sketch and beginner coding projects using microcontrollers (Arduino, ESP32, ESP8266, Raspberry Pi).
2. Power and status indicator lights for custom power supplies and DIY modules.
3. Creating custom electronic toys, decorative displays, and wearable tech.
4. Repairing or replacing broken indicator lights in household appliances and audio equipment.
