3838 (QEFM) E-Series, Low ESR, Multilayer High-Q Capacitors

(Formerly known as S58E Series)

Johanson Silver E-Series Capacitors are high RF power and low loss ceramic multilayer RF capacitors (High Frequency MLCC’s). This ultra-High-Q E-Series of products use nearly pure silver electrodes, which is a superior high frequency conductor compared to palladium. The performance of these products sets a new standard in the industry for low ESR capacitors.

Utilizing a modern dielectric system, these NP0 capacitors exhibit the lowest losses, excellent high voltage performance and excellent temperature stability.

Available in numerous termination and Lead styles, as well as custom Lead configuration
