1. Why are tantalum capacitors so expensive?
Tantalum ore resources are scarce and the mining cost is high.
The manufacturing process is complex and the yield is relatively low.
It has excellent electrical characteristics, making it indispensable in high-end applications. -
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. 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. -
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.
