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.

The chart below illustrates the spectrum of capacitor types. The dark green area is best served by capacitors made with Steinerfilm products.
