Capacitor types and application fields

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, see Tab. 1.

 

 [ F ] : = [ Farad ]
[ mF ]– Millifarad   =  [10 -3  F ]        1/1000  Farad              0.001 F        = 1000 [µF]
[ µF ] – Microfarad =  [10 -6  F ]1/1000  Millifarad0,001 [mF ] = 1000 [nF ]
[ nF ] – Nanofarad  = [10 -9  F ]1/1000  Microfarad0,001 [µF ]  = 1000 [pF ]
[ pF ] – Picofarad    = [10 –12 F ]1/1000  Nanofarad0,001 [nF ]

Tab 1: Conversion of the capacitance subunits

 

The established 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 graph below visualizes the whole spectrum. The green area is covered by capacitors with Steinerfilm products.

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
