1. Disadvantages of tantalum capacitors
The price is relatively high.
If used improperly or the circuit design is defective, it may fail, including explosion.
It is polarity sensitive and can only work in the specified direction.
It may fail easily under certain conditions (such as overvoltage, surge current). -
2. 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. -
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. 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.
