Type Aluminum Electrolytic Capacitors?
These terms (when applied to aluminum electrolytic capacitors) refer to the electrolyte type composition. The electrolyte acts as an electrical connection between the (-) cathode and the dielectric. Different forms (liquid – hybrid – solid) electrolytes have been developed over the years. Each type has benefits (PROS) and undesirable (CONS) characteristics. Development of better electrolytes has primarily focused on reducing the ESR and increasing the ripple current rating, by using higher conductivity materials. Improving the capacitor’s electrical characteristics over temperature (specifically at low temperature) and extending operational life have also been driving R&D in electrolyte development.
