From Evans Capacitor Company

Hybrid® capacitors have a lower time constant than other electrochemical capacitors. The
behavior of Hybrid® capacitors was evaluated in two applications combining high-rate discharge,
limited charging time and current, and high energy density as critical requirements. Capacitance
vs. Resistance plots are introduced as an aid to designing capacitors and comparing capacitor
perfonnance.

Products & Services
Capacitors
Capacitors are electronic components used for storing charge and energy. In their simplest form, capacitors consist of two conducting plates separated by an insulating material called the dielectric.
Power Capacitors
Power capacitors are used in electrical distribution systems to provide a static source of leading reactive power.
Chip Capacitors
Chip capacitors or surface mount capacitors do not have leads.
Tantalum Capacitors
Tantalum capacitors are used in smaller electronic devices including portable telephones, pagers, personal computers, and automotive electronics.
