1. 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. -
2. 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. -
3. 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. -
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.
