What we should pay attention when using dipped tantalum capacitors?

2023-11-16

Dipped tantalum capacitors are widely used on PCB board, but what we should pay attention when using? 

1.Polarity: they are polarized components, have a positive and negative lead.

Make sure to connect them to the circuit with the correct polarity, as reversing the polarity can damage the capacitor.

2.Voltage rating: they have a maximum voltage rating, which should not be exceeded.

Make sure to choose a capacitor with a voltage rating that is appropriate for your circuit.

3.Temperature: they are sensitive to high temperatures, which can cause them to fail.

4.Ripple current: they are often used in circuits that have a high ripple current.

5.Storage: Tantalum capacitors can degrade over time if they are stored improperly.

Make sure to store them in a cool, dry place and use them within their recommended shelf life.

6.Polarity: they are polarized components, have a positive and negative lead.

Make sure to connect them to the circuit with the correct polarity, as reversing the polarity can damage the capacitor.

7.Voltage rating: they have a maximum voltage rating, which should not be exceeded.

Make sure to choose a capacitor with a voltage rating that is appropriate for your circuit.

8.Temperature: they are sensitive to high temperatures, which can cause them to fail.

9.Ripple current: they are often used in circuits that have a high ripple current.

Etc.

Definition of dipped tantalum capacitors:  

Dipped Tantalum Capacitors, also named radial tantalum capacitors. It’s one of the most popular of the thru-hole style capacitors.

they are through-hole components that have leads that extend from the bottom of the capacitor and are bent to fit into holes on the PCB.

Comparing to SMD tantalum capacitors, they have larger size, cylindrical shape with a metal case that provides protection against mechanical damage and electrical interference.

Some applications that use a dipped tantalum capacitor are bypassing, coupling, blocking, filtering and timing in power supplies, audio circuits, TV sets, telecommunications, etc application.
