1. 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. -
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. Is tantalum better than tungsten?
It depends on the application. For capacitors, tantalum is preferred due to its unique properties; while in some other industrial uses, such as making filaments, tungsten is preferred.
-
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.
