The?full?name?of?tantalum?capacitor?is?tantalum?electrolytic?capacitor,?which?is?a?kind?of?electrolytic?capacitor.?It?uses?metal?tantalum?as?the?medium.?Unlike?ordinary?electrolytic?capacitors,?it?does?not?use?electrolyte.?Tantalum?capacitors?do?not?need?to?be?wound?with?aluminum-plated?capacitor?paper?like?ordinary?electrolytic?capacitors.?,?There?is?almost?no?inductance?by?itself.?
Since?the?dielectric?layer?of?tantalum?capacitor?is?formed?by?oxidation?of?anode?metal?in?electrolyte,?and?the?generated?dielectric?film?generates?heat?under?the?action?of?applied?voltage,?it?is?easy?to?produce?oxide?with?high?resistivity.?This?is?equivalent?to?repairing?defects,?cracks?and?other?defects?in?the?oxide?film,?that?is,?it?has?a?self-healing?effect.?This?unique?self-healing?performance?guarantees?its?long?life?and?reliability?advantages.?Solid?tantalum?capacitors?have?excellent?electrical?properties,?a?wide?operating?temperature?range,?various?forms,?and?excellent?volumetric?efficiency.?They?have?their?unique?characteristics:?the?working?medium?of?tantalum?capacitors?is?a?very?thin?tantalum?pentoxide?film?formed?on?the?surface?of?tantalum?metal.?The?oxide?film?dielectric?of?this?layer?is?combined?with?one?end?of?the?capacitor?to?form?a?whole?and?cannot?exist?alone.?Since?the?anode?block?has?many?microporous?structures,?the?capacitance?per?unit?volume?is?particularly?large,?that?is,?the?specific?capacity?is?high,?so?it?is?suitable?for?miniaturization?of?circuit?boards
The?performance?of?tantalum?capacitor?is?excellent.?It?is?a?product?with?a?small?size?and?a?larger?capacitance.

Tantalum?electrolytic?capacitors?have?the?properties?of?storing?power,charging?and?discharging,?and?are?mainly?used?in?filtering,?energy?storage?and?conversion,?symbol?bypass,?coupling?and?decoupling,?and?time?constant?components.?Pay?attention?to?its?performance?characteristics?in?the?application.?Correct?use?will?help?to?give?full?play?to?its?functions,?such?as?considering?the?product's?working?environment?and?its?heating?temperature,?and?taking?measures?such?as?debating?use.?If?used?improperly,?it?will?affect?the?product's?working?life.
In?the?working?process?of?tantalum?capacitors,?it?has?the?performance?of?automatically?repairing?or?isolating?defects?in?the?oxide?film,?so?that?the?oxide?film?medium?can?be?reinforced?and?restored?to?its?proper?insulation?capacity?at?any?time,?without?being?subjected?to?continuous?cumulative?damage.?This?unique?self-healing?performance?guarantees?the?advantages?of?long?life?and?reliability.
