Capacitator - Non-ideal Behavior - Ripple Current
... causes heat to be generated within the capacitor due to the dielectric losses caused by the changing field strength together with the current flow across the slightly resistive ... the amount of internal series resistance one would add to a perfect capacitor to model this ... Some types of capacitors, primarily tantalum and aluminum electrolytic capacitors, as well as some film capacitors have a specified rating value for maximum ripple current ...
Types Of Capacitor - Types and Styles - Electrolytic Capacitors
... Electrolytic capacitors have a metallic anode covered with an oxidized layer used as dielectric ... Electrolytic capacitors are polarized ... Aluminum electrolytic capacitors with aluminum oxide as dielectric Tantalum electrolytic capacitors with tantalum pentoxide as dielectric Niobium ...
Types Of Capacitor - Electrical Characteristics - Long Time Behavior, Aging - Life Time
... Electrolytic capacitors with non-solid electrolyte age as the electrolyte evaporates ... This evaporation depends on temperature and the current load the capacitors experience ... In contrast to ceramic, film and electrolytic capacitors with solid electrolytes, "wet" electrolytic capacitors reach a specified "end of life" reaching a ...
Tantalum Capacitor - Characteristics
... Because of its thin dielectric, a tantalum capacitor can have high capacitance in a small volume (high volumetric efficiency) ... The size and weight advantages make tantalum capacitors attractive for portable telephones, compact personal computers, and automotive electronics ... The steady-state and dynamic reliability of a tantalum capacitor are influenced by several factors under the control of the circuit design engineer ...
Electrolytic Capacitor
... An electrolytic capacitor is a type of capacitor that uses an electrolyte (an ionic conducting liquid) as one of its plates to achieve a larger capacitance per unit volume than other types, but with ... All capacitors conduct alternating current (AC) and block direct current (DC) and can be used, amongst other applications, to couple circuit blocks allowing AC signals to be transferred while blocking DC power, to ... Most electrolytic capacitors are polarized hence, they can only be operated with a lower voltage on the terminal marked "-" without damaging the capacitor ...
