What is a through hole LED?

Through hole LEDs is a type of light bead installed through holes on a circuit board, which can be used in various applications such as indicator lights and lighting. Compared to surface mounted SMD light-emitting diodes, it has higher stability and durability.

The Pickup Type of Through Hole LEDs

There are different types of pull-in for through hole LEDs, namely direct insertion, angle insertion, and mount type. The inline type has two pins and is packaged in square or cylindrical frosted plastic. The corner plug type also has two pins, but the pins are slanted and the packaging shape is cylindrical frosted plastic. The pins of the mount type are directly welded to the copper column, with loose dimensions.

Color Classification of Through Hole LEDs

Through hole LEDs can be divided into different colors such as red, green, blue, yellow, and white based on their color. When selecting the color of LED, it is necessary to filter based on the application scenario and requirements.

Service life of through-hole LEDs

When using through hole LEDs, special attention should be paid to their lifespan. The lifespan of LEDs is usually expressed in hours, which is related to factors such as heat exchange and usage current. In order to extend its service life, it is necessary to reduce its operating temperature and avoid damage caused by excessive current through appropriate heat dissipation design and reduction of operating current.

Through the above explanation, it is understood that through hole LEDs, as a common electronic component, have broad application prospects in various indicator lights, lighting and other applications. By selecting appropriate colors and pin types, various application scenarios can be achieved. Compared with surface mounted SMD LEDs, it has more stability and durability, and has a larger usage space.
