1. Disadvantages of tantalum capacitors
The price is relatively high.
If used improperly or the circuit design is defective, it may fail, including explosion.
It is polarity sensitive and can only work in the specified direction.
It may fail easily under certain conditions (such as overvoltage, surge current). -
2. Difference between ordinary capacitors and tantalum capacitors
Material: Ordinary capacitors can be aluminum electrolytic capacitors, ceramic capacitors, etc.; while tantalum capacitors use metal tantalum as anode material.
Performance: Generally, tantalum capacitors have better temperature stability and higher capacity-to-volume ratio.
Application range: Due to its performance characteristics, tantalum capacitors are often used in miniaturized electronic products that require high reliability. -
3. What is the expected life of tantalum capacitors?
Under normal circumstances, it can range from thousands of hours to tens of thousands of hours, depending on the working conditions and manufacturer specifications.
-
4. What special precautions must be taken when installing tantalum capacitors?
Ensure the correct polarity connection.
Be careful not to exceed the rated voltage.
Use appropriate fuses or other protective devices to prevent overcurrent.
Consider heat dissipation design to avoid local overheating.
