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. Will tantalum capacitors deteriorate?
Yes, tantalum capacitors may gradually lose some of their performance when stored for a long time or in adverse environments.
For example, long-term exposure to high temperature and humidity may cause the electrolyte to evaporate or chemically change. -
4. Can I use ceramic capacitors instead of tantalum capacitors?
It depends on the specific situation. If the size, ESR requirements are not high and a specific capacitance value is not required, you can consider replacing it.
But be aware that there are differences in physical properties between the two, and direct replacement may affect the working state of the circuit.
