1. What is special about tantalum polymer capacitors?
Low ESR (equivalent series resistance): They are suitable for use in circuits that require fast response.
Long life: There is no liquid electrolyte, so it will not dry out and has a longer service life.
High reliability: They perform well in long-term operation.
Self-healing ability: When a local short circuit occurs, the polymer can reform the insulating layer to prevent further damage.
Volumetric efficiency: They have a high capacitance density and can provide large capacitance values in a smaller package. -
2. 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. -
3. 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. -
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.
