"Classic wire-lead LEDs (THT LEDs) remain popular because they offer a straightforward solution for placing an indicator on the front panel of a device using a single component. Unlike SMD LEDs, they do not require external light guides. THT LEDs simply need to be mounted with sufficient accuracy on the PCB to ensure that the front panel has a proportionately sized opening," Martin Brestovič, Product Manager at SOS electronic begins the article.
Perhaps the only drawback of THT LEDs, in general, is their slightly more complex assembly process. However, this can be overcome with the use of a suitable spacer, making precise and repeatable mounting of THT LEDs on the PCB no longer an issue. It is important to note that even when handling and shaping the leads of common components like THT LEDs, basic principles must be followed. These principles are summarized in our article - Mistakes You Probably Also Make When Working with LED.
2 mm THT LED Kingbright L-13
The most commonly requested casing sizes in the THT LED segment are the so-called 3 mm and 5 mm LEDs, with the casing commonly referred to as T-1 and T-1¾.
If even the 3 mm LED is too large for your application, you can use the so-called 2 mm LED, with a casing diameter of just 2 mm. These LEDs typically have a slightly wider rear section where the LED chip and wire leads are located due to design considerations. This is also true for the THT LED Kingbright L-13 series.
In this series, the manufacturer offers three primary colours - green, yellow, and red. These are universal LEDs designed for general use, with specifications that meet the needs of most applications. Although the luminous intensity (brightness) values may seem modest at first glance, they are more than sufficient due to the small size of the LED's front face. Additionally, the coloured diffused casing ensures excellent visibility even from an angle (wide beam angle).
We have added the standard Kingbright L-13 series LEDs to our inventory, and they are now available for immediate use in your projects.
