Capacitor Types and Application Fields
Film capacitors can be found in electronic circuits for various functions and applications:
-
Noise / RFI suppression
-
Snubbers
-
High pass and low pass filters
-
Signal coupling / Decoupling
-
Motor run / Start
-
Resonant circuits
-
Grading / balancing
-
Power conditioning / power factor correction (PFC)
-
Energy storage
-
Pulsed power
-
Voltage divider
The capacitance C is defined as the ratio of electric charge Q to the voltage U between the electrodes:
The quotient of one coulomb per volt [ Amp sec / Volt ] represents the unit farad [ F ].
For commercial capacitors the following subunits are used:
The various types of capacitors are based on different dielectric materials and production methods. The capacitance ranges from picofarad to more than hundreds of farad. Voltage ratings can reach kilovolts.
