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 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. 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.
-
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.
