2024-09-03 21:29:25, Tantalum Capacitor: All Things You Need to Know
What is Tantalum Capacitor? Tantalum capacitors are small in size and can achieve large capacitance products, is first developed by the United States Bell Laboratories in 1956, its performance is excellent.
-
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 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.
