Modeling Data

PPI’s EIA High-Q Ultra Low ESR capacitor line, or N series capacitors, is specifically designed to meet the demanding requirements of High-Q and Microwave applications. These capacitors excel in environments where Low Noise, High Self-Resonance, and High Working Voltage are essential while exhibiting ultra-stable performance across a wide temperature range.

Equipped with a comprehensive set of product features (High-Q factor, High Power handling capability, Low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL), Low Noise, and High Self-Resonance), these capacitors are built to provide superior performance and reliability in critical circuit designs and deliver exceptional performance in high-frequency applications.

Functional scenarios, including tuning, bypassing, coupling, feedback, D.C. blocking, and impedance matching. Whether you are working on UHF/Microwave RF power amplifiers, mixers, oscillators, filter networks, low noise amplifiers, timing circuits, or delay lines, the N series capacitors offer excellent performance and are designed to meet the specific demands of these circuit applications.

To ensure the highest quality and reliability, the N series capacitors are designed and manufactured in accordance with the requirements set by MIL-PRF-55681 and MIL-PRF-123 and are fully compliant with RoHS (Restriction of Hazardous Substances) directive, ensuring their environmental safety. These rigorous standards guarantee that the capacitors meet the stringent specifications necessary for critical applications in aerospace, defense, and other industries where precision and durability are paramount.

The N series capacitors come in standard EIA case sizes, providing versatility and compatibility with different circuit layouts. In addition, PPI offers S-parameter files and modeling data provided by Modelithics, enabling engineers and designers to accurately simulate and optimize the performance of their circuits.

PPI provides engineers with Engineering Design Kits with predetermined values, and Custom Kits designed based on the engineer’s requirements. These kits allow designers to explore and experiment with different configurations, optimizing their circuit designs.

With the N series capacitors, you can expect outstanding performance, stability, and compliance with industry standards.
