Electrocube, design manufacturer of electronic components

Audio-optimized Film Capacitors

Designated line, custom, foil for high-end audio application

Electrocube, an audio capacitor design manufacturer, offers a full line of audio-optimized film capacitors specially designed and optimized for the high-end audio industry. Whether for professional, commercial, stage or studio applications, these audio film capacitors are preferred by audio engineers for their high grade materials and proprietary design and manufacturing processes.

How do Electrocube audio-optimized film capacitors work?

Precision-wrap and fill, oval/round and epoxy case/hermetically-sealed capacitors store energy for a number of applications such as AC and pulsing, high surges and high frequency/high current/low ESR.

What are some of Electrocube audio line of capacitor features?

  • Tolerances available from ±1% to ±20%
  • Voltages from 100 VDC to 600 VDC
  • Frequencies up to 100 KHz
  • Extended electrode construction or non-inductively wound extended foil construction with standard tin-coated, oxygen-free solid copper leads
  • Epoxy Resin endfills meet or exceed flammability requirements of UL94V0
  • Compliance and certification to worldwide and other environmental standards available upon request; RoHS and Non-RoHS available on most units
  • Rated for 100 VDC / 67 VAC, 200 VDC / 135 VAC, 400 VDC / 270 VAC, and 600 VDC / 440 VAC
