What is a polymer capacitor?

A polymer capacitor, or more accurately a polymer electrolytic capacitor, is an electrolytic capacitor (e-cap) with a solid conductive polymer electrolyte. There are four different types: Polymer Ta-e-caps are available in rectangular surface-mounted device (SMD) chip style.

What are the advantages of polymer e-caps over non-solid MLCC capacitors?

The curve of a ceramic Class 2 MLCC capacitor, with still lower Z and ESR values is also shown, but whose capacitance is voltage-dependent. An advantage of the polymer e-caps over non-solid Al-e-caps is low temperature dependence and almost linear curve of the ESR over the specified temperature range.

What is a polymer film insulating dielectric capacitor?

For capacitors with polymer film insulating dielectrics, see film capacitor. A polymer capacitor, or more accurately a polymer electrolytic capacitor, is an electrolytic capacitor (e-cap) with a solid conductive polymer electrolyte. There are four different types:

What are cylindrical polymer aluminium capacitors?

Cylindrical polymer aluminium capacitors based on the technique of wound aluminium electrolytic capacitors with liquid electrolytes. They are available only with aluminium as anode material. They are intended for larger capacitance values compared to rectangular polymer capacitors.

What is the basic unit of a polymer electrolytic capacitor?

The basic unit of a polymer electrolytic capacitor's capacitance is the microfarad (μF). The capacitance value specified in manufacturers data sheets is called the rated capacitance C R or nominal capacitance C N. It is given according to IEC 60063 in values corresponding to the E series.

What is a hybrid polymer capacitor?

In hybrid polymer capacitors liquid can flow to the defect, delivering oxygen and healing the dielectric by generating new oxides, decreasing the leakage current. Hybrid polymer Al-e-caps have a much lower leakage current than standard polymer Al-e-caps.
