1. Mechanical stability
As the wire connections of the components are fed through holes in the circuit board and soldered on the back, THT components are very robust. Their connections have a high mechanical strength, which makes them ideal for applications with high mechanical loads.
2. Mounting
THT components can be assembled easily and manually, especially for prototypes and small series production.
3. Good thermal qualities
THT components have good thermal properties, as the through-hole plating and the design ensure good heat dissipation. This is advantageous for applications with high power density.


4. High durability
Compared to SMT components, THT components can handle higher currents and voltages as they have larger and more robust designs. This makes them advantageous for power electronics.
5. Reliable in harsh environments
Thanks to their mechanical stability, THT circuits are more resistant to vibrations, shocks and strong temperature fluctuations. They are therefore well suited for applications in the aerospace, military and automotive industries.
6. Simple repair & rework
THT circuits are easy to repair or rework. The components can be easily removed and replaced, which is an advantage during maintenance because less electronic waste is produced in the long term.
