Pulse/High Voltage Capacitors

The SBE annular form factor metallized film capacitor is ideally suited for next generation pulsed power applications. Very large monolithic windings can be fabricated to replace a bank of conventional can style capacitors in order to reduce cost and simplify assembly. Capacitors can be wound on large diameter hollow cores which offer unique options for mounting and making symmetrical electrical connections.

The ring style film capacitor is perfect for low-inductance coaxial geometries to achieve very fast rise times and extremely large peak currents. The annular form factor provides a very low series ESR due to the short path length, while the large end face area significantly reduces the current density. As such, peak currents exceeding 100kA can be extracted from a 1000uF capacitor without using foil electrodes.

A wide range of individual winding configurations are available with voltages up to 8kV, and these can be utilized as building blocks to realize higher voltage architectures.

Applications include flashlamp drivers for laser systems, Marx generators, high energy pulse discharge for acoustic detection systems, and electromagnetic imaging. See our standard products specifications.
