P90 High-Q Porcelain Capacitors Expand with New Compact 0505 Case Size
Ultra-Stable, High-Q, Low ESR Porcelain P90 Capacitors for High-Power RF Applications
Sept. 2, 2026, 9:35 p.m.
Johanson Technology is pleased to announce the availability of the 0505 case size within the P90 High-Q Porcelain Capacitor family. This smaller footprint option provides engineers with greater design flexibility while maintaining the low-loss, high-reliability performance that has made the P90 series a preferred choice for demanding RF and power applications below 100 MHz.
Designed for applications where board space is limited, the new 0505 offering delivers the same key benefits of the P90 family:
- High Q performance
- Ultra-low ESR
- Stable electrical characteristics
- Non-magnetic construction
- High-reliability porcelain dielectric
- Controlled SRF and PRF behavior
- Excellent power handling capability below 100 MH
Why the 0505 Case Size Matters
As RF systems become smaller and more densely populated, engineers are increasingly challenged to maintain performance while reducing board space.
The new 0505 package enables:
- More compact RF designs
- Increased layout flexibility
- Higher component density
- Reduced PCB footprint
- Support for miniaturized RF modules and assemblies
Without sacrificing the low-loss performance required in critical RF applications.
Advantaged of P90 High-Q Technology:
When compared with conventional ceramic capacitors, P90 High-Q capacitors help engineers achieve:
- Lower insertion loss
- Improved signal integrity
- Better amplifier efficiency
- Lower heat generation
- Enhanced signal-to-noise ratio
- Increased power handling capability
