General description
BBEC Capacitor targets Optical communication system such as ROSA/TOSA, SONET and all optoelectronics as well as High speed data system or products.
The BBEC is suitable for DC decoupling, coupling and bypassing applications in all broadband optoelectronics and High-speed data system.
These capacitors in ultra-deep trenches in silicon have been developed in a semiconductor process, in order to integrate trench MOS capacitor providing high capacitance value of 10nF in a SMT 0201M. The BBEC capacitor provides very high stability of the capacitance over temperature, voltage variation as well as a very high reliability.
BBEC capacitors have an extended operating temperature ranging from -55 to 150°C, with very low capacitance change over temperature (70ppm/K).
