Specifications, models and parameters of common LED lamp beads

There are numerous types of LED chip models, including through-hole and surface mount types, as well as high-power LEDs. The LED currents range from tens of milliamperes to several amperes, while the voltage is generally consistent, mostly around 3 volts. It's challenging to generalize due to the variety of LED chip options.

In terms of packaging, LEDs can be categorized into through-hole, surface mount, and COB (Chip-on-Board) types. Based on power, they are classified into high-power, medium-power, and low-power LEDs.

Here are some common specifications and parameters for surface mount LEDs:

1. 0603 LED: In metric units, it's referred to as 1608, meaning the LED component's length is 1.6mm, and the width is 0.8mm. In the industry, it's also called 1608, while in the imperial system, it's known as 0603.

2. 0805 LED: In metric units, it's referred to as 2006, meaning the LED component's length is 2.0mm, and the width is 1.2mm. In the industry, it's called 2112, and in the imperial system, it's known as 0805.

3. 1206 LED: In metric units, it's referred to as 3528, meaning the LED component's length is 3.5mm, and the width is 2.8mm. In the industry, it's known as 3528, while in the imperial system, it's called 1206.

4. 3528 LED: This is the metric system name, indicating that the LED component's length is 3.5mm, and the width is 2.8mm. It's known as 3528 in the industry.

5. 5050 LED: This is the metric system name, indicating that the LED component's length and width are both 5.0mm. It's known as 5050 in the industry.

Currently, most manufacturers produce surface mount LED strips primarily using 3528, 5050, 3535, and 5630 models. Some also use 3528, 5050, and 1206 LEDs for automotive lighting.
