High-Q Porcelain P90 Capacitors, Case Size 2525

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

Made in North America.

Overview:

Johanson's EIA 2525, P90 capacitors are designed for high-power RF applications that demand higher voltage capability, greater power handling, and exceptionally low RF losses. Built using a high-fire porcelain dielectric, these capacitors deliver high Q, ultra-low ESR, and outstanding thermal stability, making them ideal for power amplifiers, MRI systems, semiconductor equipment, RF generators, and industrial RF applications.

The larger 2525 package supports capacitance values up to 20,000 pF and voltage ratings up to 5,000 VDC, enabling engineers to increase power capability while maintaining low insertion loss and stable electrical performance

Key Features:
