Conductive polymer capacitors can tolerate a wide operating temperature range—typically from -55° C to +105° C, and even as high as +125° C or more in some cases. High altitudes, low atmospheric pressure and even vacuum operation also have no impact on the function of conductive polymer capacitors.
Achieves low ESR by using conductive polymer for electrolytes. Major features. Very low ESR and high frequency characteristics. Stable characteristic not dependent on temperature and voltage. Higher safety than general tantalum electrolytic capacitors. An electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions.
Polymer tantalum electrolytic capacitors use high purity sintered tantalum powder as an anode with tantalum pentoxide (Ta2O5) as a dielectric and. Polymer aluminium electrolytic capacitors use a high purity and electrochemically etched (roughened) aluminium foil as an anode with aluminium oxide (Al2O3) as the Solid polymer capacitors can be used to smooth out the voltage from a power source to a sensitive circuit, reducing power noise. In such applications, they can easily replace standard electrolytic capacitors, provided that the operating voltage is sufficiently low.
