High-Q Porcelain P90 Capacitors, Case Size 7676

Ultra-Stable, Low ESR Porcelain, RF Capacitors for Low-Frequency Power Applications.

Made in North America.

Overview

Johanson's EIA 7676, P90 capacitors are designed for the most demanding RF power applications requiring maximum voltage capability, high capacitance values, and ultra-low RF losses. Manufactured using a high-fire porcelain dielectric, these capacitors provide exceptional Q, low ESR, and stable performance across extreme operating temperatures.

With voltage ratings up to 8,000 VDC and capacitance values up to 20,000 pF, the 7676 package is well suited for high-power RF generators, industrial RF systems, MRI equipment, semiconductor manufacturing, plasma generation, and high-voltage matching networks
