General description
UWSC Capacitor targets Optical communication system such as ROSA/TOSA, SONET and all optoelectronics as well as High speed data system or products. The UWSC is suitable for DC decoupling and bypass applications in all broadband optoelectronics and High-speed data system. The unique technology of integrated passive device in silicon, developed by Murata Integrated Passive Solutions, offers unique performances with high rejection up to 26+ GHz.

KEY FEATUREs
