Introduction to 3mm DIP LED Diodes

The 3mm DIP (Dual In-line Package) LED diode is a compact and highly efficient lighting component that has gained significant popularity in various industries due to its small size, low power consumption, and long lifespan. As a type of LED (Light Emitting Diode), the 3mm DIP LED emits light when an electric current passes through it, making it a versatile choice for a wide range of applications, from indicator lights to decorative lighting.

Design and Specifications

The 3mm DIP LED diode is designed with a small, round package that measures approximately 3mm in diameter. This compact size allows for easy integration into tight spaces without compromising on performance. The diode is typically mounted on a printed circuit board (PCB) and can be driven by a simple current-limiting resistor or a dedicated LED driver circuit. In terms of specifications, the 3mm DIP LED diode usually operates at a forward voltage of around 2.0 to 3.2 volts and a forward current of 20 to 30 milliamperes. These values can vary depending on the specific model and the color of the LED. Common colors include red, green, blue, yellow, and white, with some models offering a wide range of color options.
