2525 (QEEV) E-Series, Low ESR, Multilayer High-Q Capacitors


Formerly known as "S48E 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. Accordingly, the performance of these products sets a new standard in the industry for low ESR capacitors.

Utilizing a modern dielectric system, these NPO 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

Johanson has instituted a new Global Part Numbering (GPN) system.

Only the part number is changing. The parts are produced with the exact same materials, manufacturing processes, manufacturing controls, dimensions, physical attributes and testing as the parts supplied with the legacy part numbers.

The GPNs will be phased in over the next several years and are planned to be completed by January 1, 2026.

We will continue to quote and accept orders with the current (legacy) part numbers throughout this period.

Beginning January 1, 2022, all samples will be provided with the GPN.

Updates associated with this change will occur periodically.
