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. 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. -
3. 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.

4. 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.
