Product Details
5mm LED (Standard T-1 3/4 Indicator Diode)
The 5mm is the universally recognized component for simple, reliable visual indication in any electronic project. As a Light Emitting Diode, it is a semiconductor device that converts electrical energy directly into light (electroluminescence) when current flows in the forward direction.
This LED has a typical Forward Voltage (VF) requirement of approximately 2.0V and is optimally driven by 20mA of current. Crucially, the LED must always be used in series with a current-limiting resistor (calculated using Ohm's Law: R=(VSupply−VF)/IF) to prevent burnout. Its long lead identifies the Anode (+ve), and the shorter lead identifies the Cathode (-ve). With a dominant wavelength this robust component is perfect for everything from hobbyist breadboard projects to industrial status panels.
