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. 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.
-
3. Why do tantalum capacitors explode?
The main reason is that excessive voltage or current shocks cause internal short circuits, which trigger thermal runaway.
Excessive ambient temperature may also exacerbate this situation. -
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.
