Electrocube, design manufacturer of electronic components

Standard Film Capacitors

Precision electrical energy storage, varying RMS current

What types of standard precision capacitors do Electrocube manufacture and distribute?

Electrocube maintains an extensive line of standard film capacitor designs, proven consistently reliable for more than five decades.

Made from a variety of materials, including metallized polyester, metallized polypropylene, metallized polycarbonate, metallized polyphenylene, hermetically-sealed mylar, kraft and film foil, standard Electrocube precision capacitors satisfy a wide range of temperatures, capacitor insulation resistance and other configuration requirements.

How does Electrocube standard film capacitors work?

Precision-wrap and fill capacitors, oval/round/flat capacitors and epoxy case/hermetically-sealed capacitors store energy for a number of applications such as AC and pulsing, low-loss/high frequency, high frequency/high current/low ESL/ESR and high voltage. Thousands of standard Electrocube capacitors are in stock to meet each client’s needs promptly and efficiently.
