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. 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. 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.
