Power capacitors are used in electrical distribution systems to provide a static source of leading reactive power

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

Film capacitors are insulated with polyester, polycarbonate, polypropylene, polystyrene, or other dielectric materials

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

High voltage capacitors are used for storing charge and energy in high voltage applications. 

Ceramic capacitors have a dielectric made of ceramic materials

Tantalum capacitors are used in smaller electronic devices including portable telephones, pagers, personal computers, and automotive electronics. 

Aluminum electrolytic capacitors use an electrolytic process to form the dielectric. Wet electrolytic capacitors have a moist electrolyte. Dry or solid electrolytic capacitors do

Resistor, capacitor networks (RC networks) are integrated circuits (ICs) that contain resistor-capacitor arrays in a single chip

High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts

Battery and fuel cell test equipment consists of specialized test stations, stands or systems, monitors and component modules for performance or endurance testing. 

Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the receiving or second network). The purpose of matching these two impedances is to minimize wave reflection and/or to maximize the transfer of power between the system and the load

Charge and capacitive signal conditioning modules or systems amplify, attenuate, filter and/or convert a charge signal from an accelerometer, load cell, pressure transducer, displacement transducer or other type of capacitive sensor.

Ultracapacitors store charges (energy) by physically separating positive and negative charges (unlike batteries which do so chemically).  Very high power densities can be achieved by this method

Power switches are used to apply power to or remove power from instruments such as large-scale factory equipment
