Eulex Unveils the XG Series: A Groundbreaking Ceramic Capacitor Technology Offering Superior Performance for Next-Gen RF and Microwave Designs at IMS 2025, Booth 1251
With High Q, High SRF, and Low Loss, the XG Series capacitors overcome limitations and outperform existing capacitor technologies
MONTEREY PARK, Calif., June 3, 2025 /PRNewswire/ -- Quantic Eulex (hereafter, "Eulex") will showcase its XG Series Gap Capacitors at the International Microwave Symposium (IMS) from June 15th – 20th in San Francisco, CA.
A Quantum Leap in Capacitor Performance
The XG Series introduces an array of breakthrough features designed to elevate high-frequency circuit performance, providing a tenfold increase in capacitance compared to traditional solutions while maintaining Class 1 dielectric stability and High Q factors. They exhibit inherently ultra-low ESR and ESL, allowing for broader bandwidths and reduced signal loss—critical for RF and microwave systems that demand precision and reliability.
Additional key attributes include high voltage and current handling capabilities, making them suitable for the most demanding high power and high-frequency applications. Available as individual capacitors or in an array, their ultra-compact, low-profile design is suitable for surface-mount or embedded configurations. Whether integrated into small form-factor modules or large-scale antenna systems, the XG Series delivers unparalleled versatility and performance across diverse platforms.
Novel Internal Design Sets New Standards
What truly sets the XG Series apart is its revolutionary internal design:
- Embedded Top Electrode: Positioned within the dielectric, this design shortens electrode distance, significantly increasing capacitance (10X) while reducing parasitics like ESR and ESL.
- Single-Layer Construction: Unlike multi-layer ceramic capacitors (MLCCs), maintaining a true single-layer structure minimizes resistive losses and enhances high-frequency response.
- Elimination of Parasitics: Removing wire bonds, vias, and traditional terminations—primary sources of inductance and mechanical issues—results in higher reliability and cleaner signals and reduced manufacturing costs.
Industry Endorsement Highlights Impact
Sebastian Palacio, Vice President and General Manager, Planar Monolithics Industries (PMI), a leading supplier of custom, high-reliability radio frequency microwave components and subsystems covering DC to 70 GHz, emphasizes the transformative potential of this new technology:
"Our independent evaluation of Eulex Gap Capacitors (Single Layer, High-Q) has revealed outstanding performance across a range of critical parameters. The combination of lower cost, higher Q, better RF metrics (VSWR, SRF, Loss, Flatness, etc.), increased power/voltage handling, and the elimination of wire bonds represents a significant advancement in capacitor technology, very easy to install in the most critical places. These capacitors offer a compelling solution for high-performance RF designs."
