Eulex (formerly Quantic Eulex) pioneered an embedded-electrode RF capacitor architecture that delivers an order-of-magnitude increase in capacitance density with ultra-low parasitics. The result is broadband, ultra-low-loss, high-power performance across decades of frequency—ideal for DC blocking, decoupling, and impedance matching. The technology is compatible with standard surface-mount assembly processes, improving reliability, simplifying manufacturing, and reducing (or eliminating) tuning.
