1. 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.
-
2. 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. -
3. 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. -
4. What causes tantalum capacitors to burn out?
Common causes include applying a voltage exceeding the maximum allowable value, excessive current, high ambient temperature, and manufacturing defects.
