Capacitors (Latin term: condensus = compressor) are capacitive, i.e. they store electric charge. The physical unit of measure for capacity [C] (Latin term: capacitas = capacity) is Farad [F] (in honour of the English physicist and chemist Michael Faraday). Capacitors consist of two electrodes (surfaces conducting electricity) which are arranged close to each other, and a dielectric (insulating layer) in between.

Capacitors (abbr. cap) are frequency-dependent resistors. This is an important property for audio applications because capacitors can filter out low frequencies (i.e. low tones) from music signals. As the filter effect decreases with increasing frequency, the reverse conclusion is: The lower the capacity, the higher the filter effect (i.e. the higher the separating frequency).

  • Mundorf PowerCaps guarantee stabilized voltage directly at the amp. Consequently optimized for highest power pulse currents, our storage capacitors ensure extra power at the decisive moment. The result is a powerful and precise bass and a brilliant, open sound characteristics.
  • Polarised electrolytic capacitors which have the most compact design and are therefore used for very high capacities (e.g. for the voltage supply of amplifiers) cannot transfer any audio signals because audio signals are AC signals. The bipolar electrolytic capacitors of the ECap AC Audio Coupling & Signal Cap RAW series have foils with surfaces which are roughened by a special etching process thus enlarging the surface. As the capacity of a capacitor is proportional to their surface, this process provides the smallest and cheapest Mundorf audio capacitor. Bipolar electrolytic capacitors such as the ECap AC series have a second aluminium foil providing AC voltage resistance and thus making t
