(HF-coupling/ decoupling)

Blocking/Coupling

High-pass filter:

preventing DC voltages
transferring AC voltages
High insulation resistance
Low self-inductance (to observe voltage rating)
Metallized film capacitors (MK-types):
  • High capacitance values in small box sizes
  • ΔC/C over temperature: very low
  • Self-healing capability-> high withstanding voltage, high reliability
  • Very low dissipation factor (MKP)
  • High-frequency application (MKP) due to low dissipation factor
Bypass/Decoupling

Low-pass filter:

suppressing transmission of high frequencies (AC voltages)
High insulation resistance
Low self-inductance

MKS 2
MKS 4

MKP 4

Smoothing
smoothing of pulsating DC-voltages from AC-rectifier
Comparably high capacitance
Low dissipation factor (to observe frequency)

Band-pass filter (e.g. audio, TV)
pass frequencies within a certain range
attenuate frequencies outside that range
Low dissipation factor
Stable capacitance
Band-stop filter (e.g. audio, TV)
attenuate frequencies within a specific range
pass frequencies outside that range
Low dissipation factor
Stable capacitance
Timing (e.g. signal light)
when capacitor is charged voltage is increasing over time
after passing certain value a new state change occurs
High insulation resistance
Stable capacitance
Sample & hold (e.g. amplifier) analogue-digital converter:
capacitor is used to store analogue voltage value
electronic switch is used to connect/disconnect capacitor from analogue input (sampling rate)
Low dielectric absorption
High insulation resistance
Peak voltage detectors
diode conducts positive „half cycles“ to charge capacitor to peak voltage
DC "peak" stored in the capacitor, the diode is blocking current flow
capacitor retaines the peak value even if the waveform drops to zero
Low dielectric absorption
High insulation resistance
