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. How do you know that a capacitor is tantalum polymer?
Appearance markings: Usually the word "Polymer" is marked, along with the capacitance value, operating voltage, and positive and negative pole identification.
Packaging information: Check the
Technical specifications or data sheet on the product packaging. -
3. 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. -
4. What are the failure modes of tantalum polymer capacitors?
Open circuit: The internal connection is broken.
Short circuit: Caused by internal defects.
Parameter drift: This includes phenomena such as reduced capacity or increased ESR.
Explosion: This may occur in extreme cases, especially when the capacitor is subjected to excessive voltage or current.
