Polymer capacitors are advanced electrical components made with a solid electrolyte instead of a liquid one.

1. What is the difference between regular capacitors and tantalum polymer capacitors?

Construction: Regular capacitors can be non-polar (such as ceramic capacitors) or polar (such as aluminum electrolytic capacitors). Tantalum polymer capacitors are always polar and use a solid conductive polymer as the electrolyte.

Performance: Tantalum polymer capacitors generally have lower ESR, better frequency characteristics, and higher stability.

Applications: Due to their high performance characteristics, tantalum polymer capacitors are often used in electronic devices with high performance requirements.
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. Which side of a tantalum polymer capacitor is the positive pole?

Usually, there is a clear mark on the tantalum polymer capacitor to indicate the positive pole, such as a long bar mark or a "+" symbol.
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.
