967D Series - Polypropylene and Foil Audio Capacitor

Audio-optimized Film Capacitors Data Sheet

Polypropylene and Foil Audio Capacitors

The Electrocube 967D series is designed and optimized for high-end audio applications subject to AC and pulsing signals. It offers high frequency operation, high current and low ESR. As a result, the 967D series is able to handle high surge current without degrading. As part of a designated line of capacitors for high-end audio applications, audio engineers prefer the 967D series for professional, commercial stage and studio use.

Its high-grade materials, design and manufacturing process also is suitable for DC applications. Proudly made in the U.S., the 967D series is created with specialized design, testing and manufacturing techniques proprietary to Electrocube.
