Custom Feed thru Capacitor Fabrication Services

Captor offers custom feed thru capacitor fabrication services to industries that require superior electrical and electromechanical components. Feedthru capacitors provide high insertion loss across a broad band of the frequency spectrum. We utilize a unique assembly technique to offer exceptional high frequency performance. We also have an extensive stock of material to choose from and we design, engineer, and manufacture feedthru capacitors to suit your exact requirements.

Our high current and mini feedthru capacitors offer minimal to no lead inductance and have low equivalent series resistance (ESR) and high self-resonant frequency. We can design and build capacitors with voltages of 0 to 1000 VDC, 0 to 750 VAC and currents from 0 to 1000 Amps. Frequency ranges from DC to 400 can be accommodated with tolerances of ± 10%. The high current feedthru capacitors have a rugged 4-point bulkhead mounting configuration and the mini capacitors are available in bolt-in and jam nut configurations.

Captor’s feedthru capacitors suit applications in military, telecom, aerospace, and medical industries. Additional details on these products can be found in the table below or contact us today to learn about our custom high current and mini feedthru capacitors design services.
