Polymer capacitor
A polymer capacitor, or more accurate a polymer electrolytic capacitor is an electrolytic capacitor (e-cap) with a solid electrolyte of a conductive polymer. It is based on the use of an anode metal and the combination of a polymer electrolyte together with a liquid electrolyte. There are three different types: Polymer tantalum electrolytic capacitor Polymer aluminum electrolytic capacitor Hybrid polymer capacitorPolymer niobium electrolytic capacitors are not yet in production.Polymer electrolytic capacitors in rectangular SMD chip style are available with a sintered tantalum anode or with stacked aluminum anode foils. In cylindrical SMDs (V-chips) style or as radial leaded versions (single-ended) they are available only with wound aluminum anode foils.Polymer capacitors are characterized by particularly low internal equivalent series resistances (ESR) and high ripple current ratings. Their electrical parameters have similar temperature dependence, reliability and service life compared to solid tantalum capacitors, but have a very much better temperature dependence and a considerably longer service life than aluminum electrolytic capacitors with non-solid electrolytes. In general polymer capacitors have a higher leakage current rating than the other solid or non-solid electrolytic capacitors.Polymer electrolytic capacitors are also available in a hybrid construction. The hybrid polymer aluminum electrolytic capacitors may have either a solid polymer electrolyte or a liquid electrolyte. These types are characterized by low ESR values but have low leakage currents and are insensitive to transient, however they have a temperature-dependent service life similar to non-solid e-caps.Polymer electrolytic capacitors are mainly used as power supplies of integrated electronic circuits as buffer, bypass and decoupling capacitors, especially in devices with flat or compact design. Thus they compete with (MLCC), but offer higher capacitance values than MLCC capacitors. The also they display no microphonic effect.
