1. What are the disadvantages of tantalum polymer capacitors?
Higher cost: They are more expensive to produce than traditional aluminum electrolytic capacitors.
Lower withstand voltage: They are usually rated for lower working voltage than aluminum electrolytic capacitors of the same size.
Temperature sensitivity: They may not perform well in extreme temperatures, especially low temperatures.
Risk of physical damage: They may be damaged if subjected to mechanical stress or excessive current surges. -
2. Will tantalum polymer capacitors deteriorate?
All types of capacitors will experience a certain degree of aging over time. For tantalum polymer capacitors, although the aging rate is relatively slow, they may still experience problems such as capacity loss after long-term use. In addition, improper storage conditions or excessive operating temperatures can also accelerate this process.

3. What are the alternatives to tantalum polymer capacitors?
Aluminum electrolytic capacitors: For applications that do not require extremely high stability and low ESR.
Solid aluminum capacitors: Provide performance between traditional aluminum electrolytic capacitors and tantalum polymer capacitors.
Other solid capacitors: Choose the right alternative based on your specific needs. -
4. What special precautions must be taken when installing tantalum polymer capacitors?
Ensure correct polarity connection: Incorrect polarity will cause immediate damage.
Pay attention to the operating temperature range: Avoid exceeding the recommended operating temperature range.
Protection during welding: Avoid overheating to protect components from damage.
ESD protection: Take appropriate anti-static measures during handling.
