Mundorf ECap AC Bipolar Capacitors

Mundorf ECap AC Bipolar Capacitors

The ECap AC audio coupling and signal capacitors are bipolar electrolytic capacitors. These aluminium caps are used in applications where film capacitors are not suitable for reasons of space or cost, usually being a lot smaller than their film counterpart. They are heavily used in crossovers.

There are two ranges - the RAW series - the ECAP100 and ECAP63, formerly the BR100 and BR63 respectively. These are constructed of foils with surfaces are roughened by a special etching process which enlarges their surface area. As the capacitance is proportional to the surface, this process provides the smallest and cheapest solution.

Technical specifications of the ECAP100 & ECAP63:

  • capacitance range: 10uF to 800uF
  • electrical strength: 23Vac, 63Vdc (ECAP63) 35Vac, 100Vdc (ECAP100)
  • temperature range: -40 C to -85 C
  • Service life: 3000hrs Loss angle: Raw electrolytics: tan θ 0.05 @ 1kHz

The Plain series, namely the ECAP70 (formerly BG50) and the ECAP50 are made of smooth foils and are thus low loss. This has a positive effect on the sound. So if you have a choice use the Plain series.

Technical specifications of the ECAP70 & ECAP50:

  • capacitance range: 1uF to 100uF
  • electrical strength: 35Vac, 50Vdc (ECAP50) 50Vac, 70Vdc (ECAP70)
  • temperature range: -40 C to -85 C
  • Service life: 3000hrs Loss angle: Raw electrolytics: tan θ 0.025 @ 1kHz
