What do SMD LED Markings Mean?

If you’ve ever worked with SMD (Surface-Mount Device) LED lights before, you know how important it is to read the markings. SMD LED markings contain critical information for determining their electrical specifications, such as their forward voltage, brightness, color, and even their working temperature range.

In this article, we’ll go over what SMD LED markings mean and how to read them, so you can use them effectively and make informed purchasing decisions.

SMD LED Markings Basics.

SMD LEDs are small, compact components that provide high-intensity light output. The most common types of SMD LEDs are rectangular-shaped with a flat top and two or four contacts on the bottom. They can be found in a variety of applications, including smartphones, computers, keyboards, and traffic lights.

SMD LED markings can be found on the top or side of the component and are usually a combination of letters and numbers.

How to Read SMD LED Markings.

SMD LED markings are divided into two parts: the manufacturer code and the product code. The manufacturer code typically consists of one or two letters that identify the manufacturer or distributor of the component.

The product code includes a number of elements that provide specific information about the component's electrical specifications.

SMD LED Color Coding.

The first element of the product code is usually a letter or set of letters that indicate the color of the LED. For example, "W" represents white LEDs, "R" represents red LEDs, and "G" represents green LEDs.

SMD LED Forward Voltage and Brightness.

The second element of the product code is typically a number that indicates the LED's forward voltage (Vf) and brightness. The forward voltage is the minimum voltage required to turn the LED on, while brightness is measured in lumens.

For example, an LED with a marking of "3.5V" typically has a forward voltage of 3.5 volts, while an LED with a marking of "300mcd" has a brightness of 300 millicandela.

SMD LED Working Temperature Range.

The last element of the product code indicates the LED's working temperature range. This is important because LEDs can be damaged if exposed to temperatures outside their specified range.

For example, an LED with a marking of "0805" can operate within a temperature range of -40° C to +85° C.
