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. 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 is the difference between aluminum and tantalum capacitors?
Material: Aluminum capacitors use aluminum foil as the electrode material; tantalum capacitors use tantalum metal.
Performance: Tantalum capacitors generally have better high temperature performance, higher capacitance density per unit volume, and lower ESR.
Price: In general, tantalum capacitors cost more than aluminum capacitors. -
4. What causes tantalum polymer capacitors to fail?
Overvoltage operation: Exceeding the rated voltage may cause internal breakdown.
Reverse bias: Connecting the positive and negative terminals in reverse may cause immediate damage.
Overheating: Prolonged exposure to high temperature environments can affect performance and even cause failure.
Mechanical damage: Damage may also be caused by external impact or pressure.
