1. Difference between ordinary capacitors and tantalum capacitors
Material: Ordinary capacitors can be aluminum electrolytic capacitors, ceramic capacitors, etc.; while tantalum capacitors use metal tantalum as anode material.
Performance: Generally, tantalum capacitors have better temperature stability and higher capacity-to-volume ratio.
Application range: Due to its performance characteristics, tantalum capacitors are often used in miniaturized electronic products that require high reliability. -
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. When to use tantalum capacitors?
When miniaturization, low ESR (equivalent series resistance), and stable operation over a wide temperature range are required.
Suitable for audio processing, communication equipment, computer motherboards and other fields. -
4. 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.
