New Product! High-Q, Porcelain P90 Capacitors - QP Series

When designing high-power RF systems—especially below 100MHz—you need components that won’t compromise signal integrity, power efficiency, or long-term reliability. Johanson Technology’s new High-Q, Porcelain P90 Multilayer Ceramic Capacitors – QP-Series are built specifically for these challenges, delivering the performance RF engineers depend on for critical designs.

Why It Matters to Your Design:

• Low ESR and High-Q - less signal loss and improved amplifier efficiency
• High Self-resonance - enables clean, stable performance across key frequencies
• Ultra-stable P90 Dielectric - maintains capacitance across temperature swings
• Non-magnetic Construction - avoids interference in sensitive RF and MRI circuits
• Controlled SRF/PRF - supports precise tuning in matching and filter networks
• Lower Resistivity through the Heat Generation Plane – transfers heat effectively, allowing higher power dissipation

Manufactured in North America, these capacitors also support ITAR compliance, offer shorter lead times, and can be custom screened to meet application-specific requirements.

Key Specs:

• Case Sizes: 1111, 2525, 3838, and 7676
• Dielectric: High-fire porcelain for low-frequency power handling
• Temp Range: -55°C to +150°C
• Terminations: 100% Sn (RoHS) or SnPb

Typical Applications Include (but not limited to):

• MRI Coil Matching
• High Inductance Environments
• Broadband Wireless Equipment
• RF Matching & Filter Networks
• High Power Radio & Radar
• Decoupling, Bypass, & DC Block
• RF & Microwave Test Equipment
• High Voltage RF Requirements
• Semiconductor Manufacturing Equipment
