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) |

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 |
