What is LED Package (Through-the-Hole)

LED Package (Through-the-Hole) refers to a type of LED packaging that is designed for mounting onto a printed circuit board (PCB) using through-hole technology. Through-hole technology involves inserting the leads of electronic components, such as LEDs, through holes in the PCB and soldering them on the opposite side to establish a secure electrical connection.

LED packages that utilize through-hole technology are known for their robust mechanical connection, making them suitable for applications that require durability and reliability. This type of LED package is commonly used in various lighting applications, including industrial lighting, automotive lighting, and signage.

Through-hole LEDs are favored for their ability to withstand environmental and mechanical stress, as well as their resistance to heat. They offer a strong bond with the PCB, ensuring stability even in challenging conditions. Additionally, through-hole LEDs are easy to replace, making them ideal for prototyping and testing purposes. Through-hole LED packages can be found in various package styles, including round, square, triangular, and rectangular shapes, with sizes ranging from 1.80mm to 23mm. This variety of package options enables designers to choose the most suitable form factor for their specific application.

Frequently Asked Questions

Do I Need a Resistor for LED

When connecting an LED, it is essential to utilize a current-limiting resistor to safeguard the LED from the complete voltage. If the LED is connected directly to the 5 volts without a resistor, it will be excessively driven, resulting in initial brightness followed by burnout.

Can You Damage LED With Wrong Polarity

Incorrectly connecting the LED with the wrong polarity can lead to LED failure, resulting in no light emission and open-circuit LEDs. This can manifest in various ways, ranging from no visible signs of damage to physical indications such as burn marks or overheating.

What Happens When Integrated LED Goes Out

Integrated LED fixtures have a long lifespan, usually lasting for several years, sometimes even a decade or more. In the event that the integrated LED goes out, instead of purchasing a replacement LED bulb, customers can simply order a new LED array or module.

What Happens if You Wire an LED Backwards

LEDs, being diodes, have a one-way current flow, which means they only allow current to flow in one direction. Consequently, if you wire an LED backwards, it won’t light up because there will be no current flowing through it. It’s important to note that plugging an LED in backwards won’t cause any damage to the LED itself, it simply won’t function properly.
