470D Series - Polytetrafluoroethylene (PTFE) Capacitor

Audio-optimized Film Capacitors Product Data Sheets

Polytetrafluoroethylene (PTFE) Teflon® / Tin Foil Audio Capacitors

The Electrocube 470D series capacitors is part of a designated line of capacitors specially optimized for audio applications. This series adds a new dimension of sound in both sense and feel, a true luxury device for serious sound reinforcement. Top of the line for audio reproduction, the 470D series offers high frequency, high current operation in a miniature package. It’s non-inductively wound and manufactured with vigilant proprietary processes including controlled environmental conditions – critical elements that allow for years of trouble-free service. Proudly made in the U.S., the 470D series is an excellent addition to any high-end, professional, commercial or studio audio application.
