Capacitors

Capacitors are passive electronic components that store and release electrical energy by maintaining an electric field between conductive elements separated by an insulating material. They are fundamental building blocks in electronic circuits, where they help manage voltage and current behavior over time.

In general, capacitors are categorized by their construction and dielectric material, which influence their electrical characteristics and intended circuit roles.

• Energy storage: Temporarily hold electrical charge and deliver it when needed.
• Signal and power conditioning: Support circuit stability by influencing how signals and supply rails respond to changes.
• AC interaction: Provide controlled impedance to alternating signals while blocking steady-state direct current.
